Answer:

62.8

Explanation:

The volume of the cylinder is = base * height

base=Pi*radius*radius, where

base=3.1416*2*2 , height=5

Volume=3.1416*2*2*5

Volume =62.8 cubic units.

Answer:

Option B.

Explanation:

It is given that right cylinder has a radius of 2 units and a height of 5 units. It means

r = 2

h = 5

The volume of a right cylinder is


V=\pi r^2h

where, r is radius and h is height of the cylinder.

Substitute r=2 and h=5 in the above formula.


V=\pi (2)^2(5)


V=\pi (4)(5)


V=20\pi

On further simplification we get


V=62.831853


V\approx 62.8

The volume of right cylinder is 62.8 cubic units.

Therefore, the correct option is B.
