Answer 2

The option closest to the result is option A

Explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 11ft

π = 3.14

c = 2π * r

we replace with the known values

c = 2 * 3.14 * 11ft

c = 69.08ft

The length of the circumference is 69.08ft

the option closest to the result is option A
