How do you draw a 8 cm diameter circle?
Steps of construction :Draw a line segment OA=8 cm.O as centre and radius 4 cm draw a circle.Taking OA as diameter draw another circle which intersects the given circle at B and C.Join A to B and A to C.Result:AB and AC are required tangents.
What is the radius if the diameter is 7?
Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
