PLEASE HELP ME WITH THIS MATH QUESTION

Answer 1

ANSWER

301.6 ft²

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.

Answer 2

Answer:

r=4ft

h=8ft

Area of cyclender=?

by using formula,

A=πr²h

=22/7×4²×8

=402.28ft²Ans.
