Question

Mr. Lamb is missing a solution for his next patient. He has a cylindrical test tube which is 4 cm across the inside. The depth of the tube is 9 cm. What is the volume of the cylinder in mL?

Answer 1

V=113.04mL

Explanation:

The question is asking us to find the volume of a cylinder in mL. For this, we can use the equation V=
`\pi r^(2) h`.

We know the diameter, 4cm, and the height, 9cm.

In order to solve, we must first find the radius.

r=1/2d

r=1/2(4)

r=2cm

We can now plug this into our equation.

V=
`\pi r^(2) h`

V=
`\pi (2)^(2) (9)`

V=
`(3.14)(2)^(2) (9)`

V=113.04mL
