Question

Question 1 (ii)
Find the volume of the right circular cone with:
(ii) radius 3.5 cm, height 12 cm
$[Assume\pi =\frac{22}{7}]$

Answer 1

(ii) Radius (r) of the cone = 3.5 cm
Height (h) of the cone = 12 cm
Volume of the cone $=\frac{1}{3}\pi r^{2}h$
$[\frac{1}{3}\times \frac{22}{7}\times (3.5{)}^2\times 12]c{m}^3$
$=(\frac{1}{3}\times 22\times \frac{1}{2}\times 3.5\times 12)c{m}^3$
$=154c{m}^3$
