Question

The ice cream cone height is double its radius. The radius is $5.5$ cm. Find the volume of a cone.

• A. $110.126{cm}^2$
• B. $110.916{cm}^2$
• C. $348.27{cm}^3$
• D. $345.425{cm}^2$

Answer 1

The correct option is C $348.27{cm}^3$

Let $r$ be the radius of the base of the ice-cream cone and $h$ be its height.

Given, $h=2r$ and $r=5.5$cm

So, $h=5.5\times 2=11$cm

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

$=\frac{1}{3}\times \frac{22}{7}\times {5.5}^2\times 11$

$=348.27c{m}^3$
