Question

The height of a cylinder is one more than three times the radius doubled.

Which expression represents the volume of the cylinder in cubic units?

Answer 1

6πx³ + 2πx²

Explanation:

The formula for the volume of a cylinder is πr² · h.

1. Plugin the values into the formula

π2x² · (3x + 1)

2. Distribute 2πx² to (3x + 1)

6πx³ + 2πx²
