Question

The height of a cylinder is 4 units. Its radius is 5 units. What is the volume of the cylinder, in cubic units?

(Use π = 3.14)

62.8 cubic units
93.6 cubic units
314 cubic units
1,570 cubic units

Answer 1

use the volume formula for cylinder V=3.14r^2h then plug in all the info so its would be volume= 3.14*5^2*4

Answer 2

Option C is correct

314 cubic units

Explanation:

Volume (V) of the cylinder is given by:

`V = \pi r^2h` .....[1]

where,

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

As per the statement:

The height of a cylinder is 4 units. Its radius is 5 units.

⇒h = 4 units and r = 5 units

Use π = 3.14

Substitute these given values in [1] we have;

`V = 3.14 \cdot 5^2 \cdot 4`

⇒
`V = 3.14 \cdot 25 \cdot 4`

Simplify:

V = 314 cubic units

Therefore, the volume of the cylinder is, 314 cubic units
