Can someone please help me!!

[tex]\text{circumference} = \pi \times \text{diameter}[/tex][tex]\implies \text{diameter} = \frac{\text{circumference}}{\pi}[/tex][tex]= \frac{9.42}{3.14}[/tex][tex]= 3\text{feet}[/tex]

circumerence=2πr or 2 times π times radiuswe want to find diameter which is 2 times of radiusc=2(πr) using the associative property we can do 2(πr)=(2)(π)(r)=(π)(2r) and 2r=diameter so πd=circumferencec=πd9.42=πdπ≈3.149.42=(3.14)(d)divide both sides by 3.143=ddiameter=3 feet
