The circumference of a circular base of Cylinder is 44 cm and its hight is 15 cm. Then the volume of the cylinder is?

Given Circumference of a circular base of a cylinder = 44 cm

We know that Circumference of a circle =  $2\mathrm{\pi r} = 44\Rightarrow r = \frac{22}{\pi }$

Now given the height of a cylinder h = 15 cm

Volume of a cylinder $V = \mathrm{\pi r}2h = \pi \frac{22}{\pi }215 = \frac{22 x 22 x 15}{3.14} = 2311 \mathrm{cm}3.$
