How do you convert diameter to feet? Divide the length of the diameter by 2 to find the radius (12 / 2 = 6). The radius is 6 feet.
What is the formula for converting meters to feet?
example:
- 5’ 6” = 12*5 +6 = 66 inches
- 66 * 25.4 = 1676.4 mm
- 1676.4 / 1000 = 1.6774m exactly
How do you convert radius to square feet?
Square footage for a circular area. Measure the diameter of your circle in feet. To calculate the area of a circle we use the formula: π x (diameter/2) 2. That is to say π (pi is 3.14159265) multiplied by half the diameter squared. So, we divide our diameter by 2 and then square it (multiply it by itself) and then multiply by π.
How big is sq ft?
The tiniest part of our home by far is the bathroom, measuring only 30 inches wide. It was imperative we keep our bathroom clean and clutter-free, and our over-the-toilet shelf holds the toiletries we need, with room to spare. Even though our home is tiny, our sleeping loft is comfortable. Nat Cornacchione

What is the diameter of a 3 foot circle?
1 Answer. BRIAN M. The diameter is 6ft.
How do you convert diameter to square feet?
How to find the square footage of a circleMeasure the diameter of your circle in feet.Divide your diameter by 2 and then square it (multiply it by itself).Multiply your total by π (3.14159265)
What is a diameter of a circle?
2 x radiusCircle / Diameter
What is the diameter of a 7ft circle?
Answer and Explanation: The formula can be rearranged to calculate the radius so it becomes c2π=r c 2 π = r , c is 7 as given in the question so r=72π=1.1140846ft r = 7 2 π = 1.1140846 f t . The diameter is double of the radius so diameter = 1.1140846*2 = 2.2281692 ft.
What is the circumference of a 14 diameter?
Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm . You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² .
What is the radius of a circle with a diameter of 10?
Radius is the half of diameter. So radius of the circle =10/2=5cm.
What is the radius of 4 ft?
4ft * 12 in / ft = 48 in. 2r = 48 in. r = 24 in.
How many square feet is a 36 inch diameter circle?
Multiply the radius by itself to square the number (6 x 6 = 36). Multiply the result by pi (use the button on the calculator) or 3.14159 (36 x 3.14159 = 113.1). The result is the area of the circle in square feet--113.1 square feet.
How do you measure a diameter?
Just divide the circumference by π to find the diameter. For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. If you only know the area of the circle, use the formula diameter = 2 x √(area/π).
What is the area of a 5 ft circle?
The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=5 into the formula for the area of a circle. Pi π is approximately equal to 3.14 . Raise 5 to the power of 2 .
What is the difference between diameter and circumference?
The radius – the distance from the circle's center or origin to the edge, one half the diameter. The circumference – the length of the outside boundaries of the circle. Starting from the diameter, you can easily find the other two.
What is the diameter of a circle?
The diameter of a circle is the distance from edge to edge of a circle passing through its origin or center. Conveniently, it is twice as long as the radius of a circle. If you draw two opposing line segments from the circle's origin to the edge, you just drew the diameter.
What are the dimensions of a circle?
There are three dimensions most often used to describe a circle: 1 The diameter – defined above 2 The radius – the distance from the circle's center or origin to the edge, one half the diameter 3 The circumference – the length of the outside boundaries of the circle
How to calculate square footage?
To understand how to calculate square footage we must first begin with the definition of area. An area is the size of a two-dimensional surface. The area of a circle is the space contained within its circumference (outer perimeter). To find out the area of a circle, we need to know its diameter which is the length of its widest part. The diameter should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m).
What is circumference in math?
Essentially, this variable can be defined as the distance around the circle or the entire length of the circuit along the circle. The π (pi) variable is basically a constant which cannot be expressed as a fraction but applies to all calculations – including the area ...
What is the relationship between radius and diameter?
One other key relationship, radius to diameter, can also give you circumference. Radius is one half of a circle's diameter. This means we can substitute radius, r, in our formulas, using the substitution property of equality. If two radii are equivalent to one diameter, we can substitute diameter with 2 r.
What is the Greek word for circumference?
In 1706 Jones used the Greek word for circumference, περιϕέρεια, and shortened it to its first letter, π. As for π in circles, we have no one to blame but the marvel that is mathematics. Pi, or π, is the irrational number that links every circle's circumference to diameter and radius.
Can a circle be a ratio?
Circumference/Diameter. In every circle, of any size, that ratio is π. So we can use an irrational number -- a number that cannot be a ratio -- to establish a ratio. Some people say that is weird, but most mathematicians think it just shows the power of number.
User Guide
This tool will calculate the circumference of a circle from the diameter, and will convert different measurement units for diameter and circumference.
Diameter of Circle
Enter the diameter of a circle. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart.
Circumference of Circle
This is the total length of the edge around the circle with the specified diameter, if it was straightened out.
