Question

A cylinder has a height of 2 meters and a diameter that is 5 times the measure of the height. Using 3.14 for pi, which of the following can be used to calculate the volume?
(3.14)(2m)2(10m)
(3.14)(2m)2(5m)
(3.14)(10m)2(2m)
(3.14)(5m)2(2m)

Answer 1

The answer is (3.14)(5m)^2(2m)

Hope that helps <3

Answer 2

Given that diameter of cylinder is 5 times the height and height=2m, then the diameter will be:
2*5=10 m
the radius=10/2=5 m
the volume of the cylinder will be:
V=πr^2h
π=3.14
hence;
v=3.14*(5^2)*(2)
the answer is:
(3.14)(5m)^2(2m)
