    Answer:

    Exact answer = 10.41666666666666666666666666666pi

    Estimated answer = 32.70938

    Step-by-step explanation:

    Semi circle formula: 1/2 * 4/3 * pi * r^3

    r = 2.5

    1/2 * 4/3 * pi * 2.5^3

    2/3 * pi * 2.5^3

    2/3 * pi * 15.625

    10.416….. * pi

    Exact answer = 10.417pi

    We can estimate pi as 3.14

    So, 10.417 * 3.14 = 32.70938

    Exact answer = 10.41666666666666666666666666666pi

    Estimated answer = 32.70938
