Question

Which point on the number line represents the approximate volume of a cylinder with a radius of 4 units and a height of 4 units? Use 3.14 for π.

Answer 1

The volume of the cylinder is 201 u³

Explanation:

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

v = volume

h = height = 4 units

π = 3.14

r = radius = 4 units

v = (π * r²) * h

we replace with the known values

v = (3.14 * (4u)²) * 4u

v = (3.14 * 30.25ft²) * 4u

v = 50.24u² * 4u

v = 200.96 u³

Round to the nearest whole number

v = 200.96 u³ = 201 u³

The volume of the cylinder is 201 u³
