A plastic ball is filled with gel to make a stress ball. If the ball has a radius of 4 cm, how much
Dafna1 [17]

Answer:

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

Step-by-step explanation:

<em>The radius of the ball is given as 4 cm.</em>

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

The volume of the sphere is given by the formula,

V = \frac{4}{3}(\pi)R^{3} , the R is the radius of sphere.

V = \frac{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.
