Question

The volume of a right circular come is 9856 cu CM. If radius of its base is 14cm ;find the height of the cone

Answer 1

Volume of cone =
$\frac{1}{3} \pi {r}^{2}h$
$9856 = \frac{1}{3} \times \frac{22}{7} \times 14 \times 14 \times h$



$9856 = \frac{1}{3} \times 22 \times 7 \times 2 \times h$



$\frac{9856 \times 3}{22 \times 7 \times 2} = h$
$\frac{29568}{308} = h$



$96 = h$
