Question

A student is trying to calculate the density of a can. He already knows the mass, but he needs to determine the volume as well. Which of the following formulas can be used to calculate the volume of the can?

V equals four-thirds times pi times r cubed
V equals one-third times pi times r squared times h
V = s3
V = πr2h

Answer 1

Answer:

V = πr²h

Step-by-step explanation:

The student will need to use the volume formula of a cylinder. Cans usually have a cylindrical shape. After finding the volume of the can, he will then need to use the formula to find the density of the can which is Density = Mass/Volume.

Answer 2

Answer:

V=$\pi r^2h$

Step-by-step explanation:

We are given that a student is trying to calculate the density of a can .

He knows mass of can

We have to find that which formula is used to calculate the volume of can.

We know that can generally have Cylinderical shape.

We know that volume of cylinder =$\pi r^2h$

Where r=radius of cylinder

h=Height of cylinder

We can use volume of cylinder formula to calculate the volume of cylinder .

Hence, V=$\pi r^2h$
