Area of a circle is Pi * radius

The circumference of a circle is 2 * Pi * radius

C = 2 Pi r

You already know the area;

A = Pi r

= 32 Pi

so the radius is the square root of 32. Substitute sqrt(32) into 2 Pi r to get the circumference;

C = 2 Pi sqrt(32)

= 2 Pi 4 sqrt(2)

= 8 sqrt(2) Pi

= ~ 35.5

^{2}The circumference of a circle is 2 * Pi * radius

C = 2 Pi r

You already know the area;

A = Pi r

^{2}= 32 Pi

so the radius is the square root of 32. Substitute sqrt(32) into 2 Pi r to get the circumference;

C = 2 Pi sqrt(32)

= 2 Pi 4 sqrt(2)

= 8 sqrt(2) Pi

= ~ 35.5
