Question

The radius of the base of a cone is 5 cm while its height is 12 cm. Find the volume of this cone. (Take π = 3.14)

Answer 1

Radius of cone (r) = 5 cm
Height of cone (h) = 12 cm
Volume of cone = $\frac{1}{3}\mathrm{\pi }{r}^{2}h$
$$\begin{gathered} =\frac{1}{3}\times 3.14\times 5\times 5\times 12 \\ =314\mathrm{cu}\mathrm{cm} \end{gathered}$$
