\(\text{circumference} = \pi \times \text{diameter}\)

\(\implies \text{diameter} = \frac{\text{circumference}}{\pi}\)

\(= \frac{9.42}{3.14}\)

\(= 3\text{feet}\)

circumerence=2πr or 2 times π times radius
we want to find diameter which is 2 times of radius

c=2(πr) using the associative property we can do 2(πr)=(2)(π)(r)=(π)(2r) and 2r=diameter so
πd=circumference
c=πd
9.42=πd
π≈3.14
9.42=(3.14)(d)
divide both sides by 3.14
3=d
diameter=3 feet
