Find the volume of a cylinder with a height of 5 meters and a diameter that is 4 times the measure of the height. Use 3.14 for pi and round your answer to the nearest hundredth. 62.8 m3 251.2 m3 678.24 m3 1570 m3

OpenStudy (anonymous):

height=5 meters. So the diameter=20 meters. \[V=height*diameter*3.14\]

OpenStudy (anonymous):

D I think. 1570 m3

OpenStudy (ipwnbunnies):

Uh, that's incorrect, Charlie.

is Eurowo corretc bunnsies

OpenStudy (ipwnbunnies):

Yes, it'd D. \[V = \pi r^2 h\] The height is 5 meters. The diameter is 20 meters, so the radius is 10 meters. You can do the math.
