What is pi times r2?

pi times radius or diameter equals are of a cirlce

The radius of a circle is 5 inches What is the circumference of the circle?

Circumference is 2 times pi times radius, so the circumference of this circle is 2 times pi times 5, or 10 times pi. If a decimal answer is needed, pi is approximately 3.14, so C=31.4

What is Pi times radius times radius?

The answer is Pi times radius squared. Although you can't know anymore since you don't give what the radius is. Although, Pi can be simply referred to as 3.14

Is the circumference greater than the diameter?

No. Circumfrence=2 times pi times radius. And since the daimeter = 2 times radius, circumference is diameter times pi.

How do you find the diameter of a cylinder from the area of the base?

The area of the base of a cylinder = Pi times Radius squared. Diameter of a cylinder = 2 times Pi times Radius. To find the diameter derive the area of the base by Pi and then square root the answer. That will give you the value of the radius. Multiply that answer by 2 times Pi and you will have your answer.
