Question

What is the surface area of the right cylinder below?

Answer 1

Answer: c

Step-by-step explanation: r= 8 h=3

1. write your formula=
   `2\pi rh+2\pirx^(2)`

2. now substitute
`2\pi 8*3+2\pi 8x^(2)`

3.
`176\pi unit squared` - answer

Answer 2

C - the surface area of a cylinder = 176πunits²

Explanation:

to evaluate the surface area of a cylinder

whose radius = 8units

height = 3units

recall that the surface area of a cylinder = 2πrh + 2πr²

the surface area of a cylinder = 2 x π x 8 × 3 + 2 x π x (8)²

the surface area of a cylinder = 2π24 + 2π x 64

the surface area of a cylinder = 48π + 128π

the surface area of a cylinder = 176πunits²
