Question

A plastic ball is filled with gel to make a stress ball. If the ball has a radius of 4 cm, how much

gel will fill the ball?

Answer 1

267.947 cm^{3} of gel is required to fill the plastic ball.

Explanation:

The radius of the ball is given as 4 cm.

The gel is filled in the plastic ball, that means the gel occupies the volume of the radius.

The volume of the sphere is given by the formula,

`V = (4)/(3)(\pi)R^(3)` , the R is the radius of sphere.

`V = (4)/(3)(\pi)(4)^(3) = 267.947 cm^(3)`

Thus, the volume of gel required to fill the plastic ball to make it stress ball is

267.947 cm^{3} of gel.
