A right cylinder has a diameter of 40 mm in a high of 30 mm as soon what is the volume of the cylinders

Hey!!

Solution,

Diameter=40 mm

Radius=40/2=20mm

Height=30mm

Volume of cylinder=?

Now,

Volume of cylinder=pi (r)^2 h

= 3.14*(20)^2*30

=3.14*400*30

=37,680 mm^3

So the right answer is of option A

hope it helps

Good luck on your assignment

37,680 mm3

Steps:

Formula: Volume = Area * height

1:    = (pi/4)*D^2 * h

2:   = (pi/4)*(40)^2 * 30  

3:    = 37,680 mm3

Description:

We know that r is the radius and h is the height. So the

radius of the cylinder going to be r=40/2=20mm

Height of cylinder: 30mm

Meaning when you add up all the numbers answer will come as  37,680 mm3.  So a is the right answer for this question.

A.   37,680 mm3
