PLEASE HELP ME WITH THIS MATH QUESTION

Answer 1

r=4ft

h=8ft

Area of cyclender=?

by using formula,

A=πr²h

=22/7×4²×8

=402.28ft²Ans.

Answer 2

301.6 ft²

Step-by-step explanation

The surface area of a cylinder is calculated using the formula;

`S.A = 2\pi \: r(r + h)`

From the diagram the height of the cylinder is 8 feet and the radius is 4 feet.

We substitute the values into the formula to obtain,

`S.A = 2\pi \: 4(4+ 8)`

This simplifies to:

`S.A = 8\pi \: (12)`

`S.A = 96\pi`

Or

`S.A = 301.6 {ft}^(2)`

to the nearest tenth.
