Answer 1

To do this, we have to multiply the 7 feet diameter by pi to get the circumference because the formula for circumference is $C = \pi *d$, or circumference = pi times diameter. 7 x 3.14 (pi rounded) = 21.98

Answer: 21.98 feet

Answer 2

Circufmernece=pi times diameter
given that diameter=7ft

circumfernece=7ft times pi
circumfernce=7π ft or aprox 21.98ft
