Question

Bridget has a kitchen canister, in the shape of a cylinder, which holds flour. If the canister is 20 centimeters wide and 28 centimeters tall, what is its approximate surface area in terms of pi?
Answer
1,920π square centimeters
1,120π square centimeters
760π square centimeters
560π square centimeters

Answer 1

suface area of a cylinder = 2πrh

where
r = radius, d/2, width ?/2
h = height

A = 2π(20/2)(28)
A = 560π square centimeters

Answer 2

so this one is like where you use \[2\pi rh + 2\pi r ^{2}\] ??

Answer 3

i think what you put would be the lateral area

Answer 4

Ah, yeah use your formula 2πrh+2πr^2
A = 560π +200π

A = 760π

Answer 5

C:) 760π square centimeters
