Question

A ball has a radius of 18 cm.

What is the approximate volume of the ball?

Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.

Enter your answer in the box.

Answer 1

The approximate volume of the ball is, 24,416.64 cubic cm

Explanation:

Volume of a sphere is given by:

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

where,

V is the volume of the sphere

r is the radius of the sphere.

As per the statement:

A ball has a radius of 18 cm

⇒
`r = 18 cm` and use
`\pi = 3.14`

Substitute these in [1] we have;

`V = (4)/(3)\cdot 3.14 \cdot  (18)^3`

⇒
`V = (4)/(3) \cdot 18,312.48`

Simplify:

`V = 24,416.64 cm^3`

Therefore, the approximate volume of the ball is, 24,416.64 cm^3
