Question

Ok yo
Radius of 23 feet. What is the circumference ?

Answer 1

C = 46pi ft (exact answer)

C = 144.5 ft (approximate answer)

Explanation:

C = 2 * pi * r

C = 2 * pi * 23 feet

C = 46pi ft (exact answer)

C = 144.5 ft (approximate answer)

Answer 2

Circumfrence is pi*diameter. Radius is half the diameter, so..

23*2=46

And 46*pi

= 46pi
