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

Answer:

[tex]v = 113.0 \: {inches}^{3} [/tex]

Step-by-step explanation:

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

[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]

Where,

Pi = 3.14; r = 3 in

[tex]v = \frac{4}{3} \times 3.14 \times {3}^{3} [/tex]

[tex]v = \frac{4}{3} \times 3.14 \times 27 {in}^{3} [/tex]

[tex]v = 1.3 \times 3.14 \times 27[/tex]

[tex]v = 113.04 {in}^{3} [/tex]

[tex]v = 113.0 \: {inches}^{3} \: ( to \: nearest \: tenth)[/tex]
