Question

Find the volume of the coneheight of 7 cmbase radius 3 cmuse the value 3.14 for pie

Answer 1

Solution

- The volume of a cone is given by the formula below

$\begin{gathered} V=\frac{1}{3}\times\pi\times r^2\times h \\ \text{where,} \\ r=\text{radius of the base of the cone} \\ h=\text{height of the cone} \end{gathered}$

- The question has given us the radius to be 3 cm and a height of 7 cm. Thus, we can calculate the volume of the cone.

- The volume of the cone is given by

$\begin{gathered} r=3,h=7,\pi=3.14 \\ V=\frac{1}{3}\times\pi\times3^2\times7 \\ \\ \therefore V=65.94cm^3 \end{gathered}$

Final Answer

The volume of the cone is 65.94 cm³
