Question

Suppose the radius of a circle is 16. what isSuppose the radius of a circle is 16. what is its circumference its circumference

Answer 1

The circumference is 2r pi
2*16*pi=32pi

32 pi = 100.530964915
Hope this helps

Answer 2

C = 32 * pi or approximately 100.48

Explanation:

The formula for circumference is

C = 2*pi*r

We know the radius is 16

C = 2*pi*16

C = 32 pi

or if we approximate pi as 3.14

C = 32 *3.14

= 100.48
