Question

A right cylinder has a radius of 2 units and a height of 5

Answer 1

Answer:

62.8

Step-by-step 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 2

Answer:

Option B.

Step-by-step 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.
