Solve for the balloon volume using the equation below
valentinak56 [21]

The volume of the balloon is 1441.64cm³.

<h3>How to calculate the volume?</h3>

The radius of the balloon is given as 7cm. Also, the equation to calculate the volume is given as c³/6π²

The circumference c will be:

= 2πr = 2 × 22/7 × 7

= 44

The volume will be:

= c³/6π²

= 44³/(6 × 3.14²)

= 85284/(59.1576)

= 1441.64
