Question 1 (i)
Find the volume of the right circular cone with:
(i) radius 6 cm, height 7 cm.
$[Assume\pi =\frac{22}{7}]$

Answer 1

(i) Radius (r) of the cone = 6 cm
Height (h) of the cone = 7 cm
Volume of the cone $=\frac{1}{3}\pi r^{2}h$
$=[\frac{1}{3}\times \frac{22}{7}\times (6{)}^2\times 7]c{m}^3$
$=(12\times 22)c{m}^3$
$=264c{m}^3$
