Question

What is the volume of a cone with the diameter 12 CM in height 4 cm

Answer 1

The formula for the volume of a cone is

`V=\pi\cdot r^2\cdot(h)/(3)`

to find the radius divide the diameter by 2

`\begin{gathered} r=(D)/(2) \\ r=(12)/(2) \\ r=6 \end{gathered}`

replace all data in the formula

`\begin{gathered} V=\pi\cdot(6^2)\cdot(4)/(3) \\ V=\pi\cdot36\cdot(4)/(3) \\ V=(48\pi)cm^3^{} \end{gathered}`
