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

height 3
radius 8

a. 144pie units squared
b. 192pie units squared
c. 72pie units squared
d. 176pie units squared

D

Step-by-step explanation:

The surface area is the area of all the surfaces. The surface area of cylinder has the formula:

Where

r is radius

h is height

r is 8

h is 3

Substituting, and keeping as is, we have:

Thus,

Surface Area =  units squared, answer choice D is right

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
