Sphere

Bowling ball


The purpose or function of the bowling ball is to play the game known as bowling.

Radius of bowling ball is 4.25 inches or 10.8 centimeters

Sphere


Surface Area of a Sphere = 4 X π X r²

SA= 4(π) (10.8) 2
Approximate= 1465.74 cm²
Exact= 1465.741468 cm²

Why is this Important?

Knowing the surface area of a bowling ball helps determine the angle the bowiling ball will go when you roll it.

Volume of a Sphere = (4/3) πr³

SA= (4/3) (π) (10.8)³

Approximate= 1319.17 cm³
Exact= 1319.167322 cm³

Why is this Important?

Knowing the volume of a bowling ball could be usefull in helping determine the weight of the sphere.
