## What is the area of the circumference is 10 pi?

So, the radius is 10pi=2pir. If we divide 10pi by 2pi to get the radius by itself, r=5. The area of a circle, meanwhile, is 2pi(r^2). 5 squared is 25, so the area becomes 50pi, as 2×25=50.

## How do you find circumference when given the area?

Like many things in math, there are multiple solutions to this problem. The formula C = 2√πA is designed to find a circle’s circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation.

## What is the circumference of a circle whose area is 100π?

20 pi

## What is the circumference of a 10cm circle?

31.42cm

## What is the radius of a 5cm circle?

r = 0796 is right answer.

## What is the radius of a circle with a circumference of 18 pi?

To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.
