    Answer:

    v = 113.0 \:  {inches}^{3}

    Step-by-step explanation:

    Formula for finding the volume of a sphere is given thus:

    v =  \frac{4}{3} \pi {r}^{3}

    Where,

    Pi = 3.14; r = 3 in

    v =  \frac{4}{3}  \times 3.14 \times  {3}^{3}

    v =  \frac{4}{3}  \times 3.14 \times 27 {in}^{3}

    v = 1.3 \times 3.14 \times 27

    v = 113.04 {in}^{3}

    v = 113.0  \: {inches}^{3} \: ( to \: nearest \: tenth)

    Answer:

    9.4 inches

    Step-by-step explanation:

    Set up the equation: V = πr²

    Plug in 3: V = π(3)²

    Square 3: V = 3π

    Multiply 3 by π: V = 9.42

    Round: V = 9.4
