Question

What is the volume of a cylinder with a height of 5.8cm and radius of 2.1 cm? Show work

Answer 1

Answer:80.31492 cubic centimeter

Explanation:

π=3.14

radius=2.1cm

Height=5.8cm

volume of cylinder=π x radius x radius x height

Volume of cylinder=3.14x2.1x2.1x5.8

Volume of cylinder=80.31492

Answer 2

The volume of the cylinder is 80.3cm³

Explanation:

To calculate the volume of a cylinder we have to use the following formula:

v = volume

h = height = 5.8cm

π = 3.14

r = radius = 2.1cm

v = (π * r²) * h

we replace with the known values

v = (3.14 * (2.1cm)²) * 5.8cm

v = (3.14 * 4.41²) * 5.8cm

v = 13.85² * 5.8cm

v = 80.3cm³

The volume of the cylinder is 80.3cm³
