Question

The volume of a cylinder is 47x cubic units and its height is x units.
Which expression represents the radius of the cylinder, in units?
O 2x
O 4x
O 2pix2
O 4pix2

Answer 1

Answer:

2x

Step-by-step explanation:

The volume of the cylinder is given by the following formula:

pi.r².h

4pix³ = pi x r² x x

r² = 4pix³/pix

r² = 4x²

Rooting both sides

r = 2x
