Question

Which of the following is the surface area of the right cylinder below?

Answer 1

`\text{The surface area of right cylinder is }352\pi units^2`

Explanation:

Given radius and height of right cylinder

we have to find the surface area of right cylinder.

Radius=8 units

Height=14 units

`\text{surface area of right cylinder=}2\pi r(r+h)`

`=2\pi (8)(8+14)`

`=16\pi(22)=352\pi units^2`

`\text{The surface area of right cylinder is }352\pi units^2`

Option B is correct.

Answer 2

surface area of cylinder = 2*pi*r*h + 2*pi*r^2

= 2*8*14*pi = 224pi

+ 2*8^2*pi = 128 pi

224+128 = 352

so answer is 352 pi
