Question

Find the circumference of a a circle with an area of 530.93 square meters

Answer 1

The circumference is 26
`\pi`

To find this we must start by finding the radius of the circle. You can find this using the formula for area adjusted to find the radius.

r =
`\sqrt{ (A)/( \pi )}`

Then when we plug the area in for A, we get the radius to be 13.

We can then use that number in the circumference formula which is below.

C = 2
`\pi`r

Using that we can find the circumference to be 26
`\pi`
