Question

Find the volume of a cone of height 7 cm and a base radius of 9 cm.

Answer 1

Radius of cone (r) = 9 cm
Height of cone (h) = 7 cm
Volume of cone =$\frac{1}{3}\mathrm{\pi }{r}^{2}h$
$$\begin{gathered} =\frac{1}{3}\times \frac{22}{7}\times 9\times 9\times 7 \\ =594\mathrm{cu}\mathrm{cm} \end{gathered}$$
