Question

How much helium is in the ballon if the ballon has a radius of 11 cm? Round to the nearest tenth and use 3.14

Answer 1

5572.5 cubic cm.

Explanation:

A balloon is in a spherical shape. The amount of helium in the balloon is determined by the volume of the balloon.

The volume of a sphere is calculated using the formula:

`V=(4)/(3)\pi r^3`

Given that the radius of the balloon = 11 cm

`\begin{gathered} V=(4)/(3)*3.14*11^3 \\ =5572.453 \\ \approx5572.5\;cm^3 \end{gathered}`

The volume of helium in the balloon is 5572.5 cubic cm.
