Question

Ariel is filling a giant beach ball with air. The radius of the beach ball is 30 cm.
What is the volume of air that the beach ball will hold?

Answer 1

Given:

(i) Ariel is filling a giant beach ball which has a radius of 30cm with air.

To find:

(i) The volume of air it can hold.

Solution:

The beach ball is spherical in shape.

We know, that a sphere of radius 'r', has a volume V, given by:

V = (4/3)Пr³

Here, the radius(r) is = 30cm.

V = (4/3)П(30)³

Taking П as 3.14, we get

V = (4/3)(3.14)(30)³

= 113040 cm³

So, the ball can hold 113040 cm³.
