Answer:

d)96π

Step-by-step explanation:

Given:

Cyliner with radius,a= 4

Height b=8

Surface area of cylinder, A=2πrh+2πr^2

=2π(rh+r^2)

=2π(4(8) + 4^2)

= 2π(32+16)

 =2π(48)

 =96π !

Answer: Option D.

A =96\pi\ cm^2

Step-by-step explanation:

The area of the circular bases is:

A_c = 2\pi(a) ^ 2

Where

a=4\ cm is the radius of the circle

Then

A = 2\pi(4) ^ 2

A = 32\pi\ cm^2

The area of the rectangle is:

A_r=b * 2\pi r

Where

b=8\ cm

b is the width of the rectangle and 2\pi r is the length

Then the area of the rectangle is:

A_r=8 * 2\pi (4)

A_r=64\pi\ cm^2

Finally the total area is:

A = A_c + A_r\\\\A = 32\pi\ cm^2 + 64\pi\ cm^2\\\\

A =96\pi\ cm^2
