    Answer:11.9 inches

    Step-by-step explanation:

    Circumference(c)=75inches

    Pi=3.14

    Circumference(c)=2 x π x radius(r)

    75=2 x 3.14 x r

    75=6.28 x r

    Divide both sides by 6.28

    75 ➗ 6.28=(6.28 x r) ➗ 6.28

    11.9=r

    Therefore radius=11.9 inches

    Answer:


    1)  12in


    Step-by-step explanation:

    The circumference is 75, so to find the diameter you have to divide 75 by 3.14. You get 24 approximately. Then divide the diameter by 2, so 24/2=12.

    Your error: pi is 3.14 not 3.24
