Question

Find the volume of the shape.Round to 2 decimal places.22 cm14 cm

Answer 1

Given:

The figure given is a cone.

`\begin{gathered} where: \\ d=14cm \\ h=22cm \\ \\ Hence,\text{ } \\ r=(d)/(2)=(14)/(2) \\ r=7cm \end{gathered}`

The volume of a cone is given by:

`\begin{gathered} V=(1)/(3)\pi r^2h \\ V=(1)/(3)*\pi*7^2*22 \\ V=(1078\pi)/(3) \\ V=1128.879 \\ \\ To\text{ 2 decimal places;} \\ V\approx1128.88cm^3 \end{gathered}`

Therefore, the volume of the cone is 1128.88 cubic centimeter.
