Question

The height of a right circular cylinder is $14cm$ and the radius of its base is $2cm.$ Find its total surface area.

Answer 1

We know that the total surface area of a right circular cylinder with radius $r$ and height $h$ is $TSA=2\pi r(r+h)$.

It is given that the height is $h=14cm$ and the radius is $2cm$. So,

$TSA=2\pi r(r+h)$

$=2\times \frac{22}{7}\times 2(2+14)$

$=\frac{88}{7}\times 16$

$=\frac{1408}{7}$

$=201.14{cm}^2$

Hence, the total surface area is $201.14c{m}^2.$
