Question

Find the volume of a cone as shown in the above figure: (Use $\pi =\frac{22}{7}$)

(Round off your answer to the nearest whole no.)

• A. $1650{mi}^3$
• B. $1550{mi}^3$
• C. $1500{mi}^3$
• D. $1620{mi}^3$

Answer 1

Answer: (A)

$1650{mi}^3$

Given, $h=63mi$ and $r=5mi$.

We know, Volume of a cone $=\frac{1}{3}\times \pi r^{2}h$

$=\frac{1}{3}\times \frac{22}{7}\times 5\times 5\times 63$

$=1650{mi}^3$.

Hence, option $A$ is correct.
