Question

Which Unit Measure would be appropriate for the volume of a cylinder that is 8 meters tall and has a radius of 4 meters?

A. Meters B. Square meters C. Centimeters D. Cubic meters

Answer 1

The volume is always written in cubic units.

Therefore your answer is D. Cubic meters.

Answer 2

Answer: Option 'D' is correct.

Explanation:

Since we have given that

Radius of cylinder = 4 meters

Height of cylinder = 8 meters

We need to find the volume of cylinder.

As we know the formula for "Volume of cylinder ":

`Volume=(1)/(2)\pi r^2h\\\\Volume=(1)/(2)* (22)/(7)* 4* 4* 8=201.14\ m^3`

As we can see that while calculating volume we consider radius two times and height one time.

So, it has 3 dimensions or units.

So, Unit measure of volume should be in cubic and both the dimensions are given in meters.

Hence, Unit measure of volume is cubic meters.

Thus, Option 'D' is correct.
