Question

An inflatable beach ball has a circumference of 141.3 centimeters what is the volume of the beach ball when fully inflated

Answer 1

The volume of fully inflated ball is 47688.75 cubic centimeter

Step-by-step explanation:

Step 1 :

The circumference of the given beach ball = 141.3 centimeters

We need to find volume of the inflated ball

Step 2 :

Circumference  = 2 $\pi$ r = 141.3 [r is the radius]

=> r =  22.5 [ This is obtained by dividing 141.3 by 2  $\pi$]

The volume of the fully inflated ball is the volume of a sphere with the radius 22.5

Therefore volume = (4/3)  $\pi$ r³ =  (4/3)  $\pi$ (22.5)³ = 47688.75 cubic centimeter

Step 3 :

Answer :

The volume of fully inflated ball is 47688.75 cubic centimeter
