Question

Find the lateral area, total area, and volume for the cylinder with the given measurement. r = 4, h = 5

Answer 1

helllppp plzzzz lol

Answer 2

they want the answers in pi

Answer 3

V = πr2h
surface area is:
the area of the top (πr2) +
the area of the bottom (πr2) +
the area of the side (2πrh).

Therefore without the top or bottom (lateral area), the surface area is:
A = 2πrh.

surface area is:
A = 2πr2 + 2πrh

Lateral Area = 32pi
Area = 72pi
Volume = 80pi
