Question

A ball has a radius of 18 cmWhat is the approximate volume of the ball? Use 3.14 to approximate pi. Round to the nearest hundredth if necessary.

Answer 1

The volume of the ball can be estimated using the volume of a sphere.

The volume of a sphere is:

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

Where:

V = volume

r = radius

Knowing that r = 18 cm and using π = 3.14, let's substitute the values in the formula and find the volume:

`\begin{gathered} V=(4)/(3)*3.14*18^3 \\ V=(4)/(3)*3.14*5832 \\ V=24416.64cm^3 \end{gathered}`

Answer: The volume of the ball is 24416.64 cm³.
