Question

Find the total service area of a right circular cylinder whose radius is 10 cm and whose height is 7 cm.

Answer 1

Given:

Radius of cylinder is, r = 10 cm.

Height of the cylinder is, h = 7 cm.

The objective is to find the total surface area of the right circular cylinder.

The formula to find the total surface area is,

`\text{TSA}=2\pi r(h+r)`

Now, substitute the given values in the above equation.

`\begin{gathered} \text{TSA}=2\pi10(7+10) \\ =20\pi(17) \\ =340\pi \\ =1068.14cm^2 \end{gathered}`

Hence, the total surface area of the cylinder is 1068.14 sq. cm.
