Volume of Cylinders

What does the 'B' in the volume formula V = Bh stand for?

• B stands for the area of the base.

• B stands for the height of the object.

• B stands for the volume of the object.

• B stands for the perimeter of the base.

What is the formula for the volume of a cylinder?

• V = πr²h

• V = 2πrh

• V = πr² + h

• V = πr²h²

If the radius of a cylinder is doubled, how does that affect the volume?

• The volume remains the same.

• The volume increases by a factor of two.

• The volume increases by a factor of three.

• The volume increases by a factor of four (V = π(2r)²h = 4πr²h).

What does 'r' represent in the volume formula V = πr²h?

• The height of the cylinder.

• The diameter of the base of the cylinder.

• The radius of the base of the cylinder.

• The circumference of the base of the cylinder.

What does 'h' represent in the volume formula V = πr²h?

• The radius of the cylinder.

• The diameter of the cylinder.

• The height of the cylinder.

• The circumference of the cylinder.

What is the formula for the volume of a prism?

• V = Bh, where B is the area of the base and h is the height.

• V = lwh, where l is the length, w is the width, and h is the height.

• V = 1/3Bh, where B is the area of the base and h is the height.

• V = 2πr^2h, where r is the radius of the base and h is the height.
