What is the volume of a cylinder with a radius of 5 centimeters and height of 2.5 centimeters?
IRISSAK [1]

Answer:

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h    where r is the radius and h is the height.

We are given r = 5 and h = 2.5, plug those values in and simplify...

V = π(5²)(2.5)

       V = π(25)(2.5)

              V = 62.5π
