Using the volume of a cylinder formula. Calculate the volume of the cylinder. *
Romashka [77]

Answer:

The first answer choice: 15 cm x 3.14 cm x 2cm^2 = 188.4 cm^3

Step-by-step explanation:

Formula:

V=πr^2h

radius=2

height=15

V=π(2)^2*15

π(4)*15

4*15=60

60π

π=3.14

60(3.14)

188.4

Since its volume you have to cube it

188.4 cm^3
