3.21 ft.

anonymous · Answer

use the formula for the circumference
2 x pi x radius

anonymous · Answer

circumference = 2 π r
                         = 2 * 3.14 * 3.21
                         = 20.159 ft

If u use π as 22/7, then

circumference = 2 π r
                                     22
                         = 2 * ----- * 3.21
                                      7
                         = 20.177 ft
