Question

Can you please help me out with a question

Answer 1

The volume of the ball (a sphere) is

`V=(4)/(3)\pi r^3`

However, half of the sphere is

`V=(2)/(3)\pi r^3`

When r = 3, the volume is

`\begin{gathered} V=(2)/(3)*\pi*3^3 \\ V=(2)/(3)*\pi*27 \\ V=56.549 \end{gathered}`

Therefore, the answer is 56.549 ft³ (OPTION A)
