Question

2. TOYS A playground ball has a radius of

7.5 inches. Find the volume of the ball.
Round to the nearest tenth.
What would the answer be

Answer 1

1,766.3 in³

Explanation:

Volume = (4/3) × pi × r³

= (4/3) × 3.14 × 7.5³

= 1,766.25

Answer 2

1767.1 inches cubed

Explanation:

The volume of a ball, or a sphere, is:
`V=(4)/(3) \pi r^3` , where r is the radius.

Here, the radius is r = 7.5. So, plug in this value:
`V=(4)/(3) \pi *(7.5)^3=562.5\pi`

562.5 pi is about 1767.1 inches cubed.

Thus, the volume is 1767.1 inches cubed.

Hope this helps!
