Question

The height of a cylinder is twice the radius of its base.

2x
What expression represents the volume of the cylinder,
in cubic units?
○ 4.7x²
Ο 2πχ"
O
x² + 2x
2 + x³

Answer 1

• height=h=2x
• radius=r=x

Volume

• πr²h
• π(x)²(2x)
• 2πx(x²)
• 2πx³

Option B

Answer 2

It would be the 3rd option, pi(x2)+2x.
