Question

please HELP!
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

Answer 1

What's the formula to find the volume of a cylinder?

Answer 2

V
=
π
r
2
h

Answer 3

Yup, so now just plug in the height, radius (which is half of the diameter) and the pi and solve!

Answer 4

THIS IS SO HARD

Answer 5

V=hpir^2
d=4h
r=d/2
r=4h/2
r=2h
h=5
so r=10

V=5*pi*10^2
V=(5)(100)(3.14) = ?

Answer 6

its 1575

Answer 7

1570
