Question

Find the volume of the right circular cone with
i) Radius $6cm$, height $7cm$
ii) radius $3.5cm$, height $12cm$

Answer 1

Volume of cone $=\frac{1}{3}\pi r^{2}h$

$\left(a\right)\frac{1}{3}\times \frac{22}{7}\times 6\times 6\times 7$ $\left(b\right)\frac{1}{3}\times \frac{22}{7}\times 3.5\times 3.5\times 12$

$=264c{m}^3$ $=154c{m}^3$
