Aright cylinder has a radius of 2 units and a height of 5
units.
what is the volume of the cylinder? round to the nearest
tenth.
31.4 cubic units.
62.8 cubic units
157.1 cubic units
314.2 cubic units.

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

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

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

On further simplification we get

The volume of right cylinder is 62.8 cubic units.

Therefore, the correct option is B.

answer: x

step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
