  • [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 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
