Question

Find the radius of a circle with the given circumference. 6√2pi in. r =

Answer 1

r = 3sqrt*2

Explanation:

We'll need the formula for the circumference of a circle: C = 2*pi*r

This can be solved for r:

C

r = -----------

2*pi

Here, with C = 6sqrt(2)*pi,

6sqrt(2)*pi

r = ------------------ = 3sqrt*2

2*pi
