  • The diameter is 3 feet.
    [tex]9.42/3.14=3[/tex]
    So,the answer is 3 feet.

  • 9.42

    ((x)(y) means x times y)

    circumference=2 times pi times radius or 2(πr) and we notice that we can play with the distributive property and get 2(πr)=(2)(π)(r)=(π)(2r) and 2r or twice of r=diameter so 2πr=πdiamater

    so
    9.42=π(diameter)
    divide both sides by π aproxamated in this question to be 3.14
    9.42/3.14=diameter=3
    the diameter is 3 feet
