Volume - Cylinders, Cones & Spheres

What is the formula for the volume of a cylinder?

• Volume = πr²h, where r is the radius and h is the height.

• Volume = 2πr²h, where r is the radius and h is the height.

• Volume = πr² + h, where r is the radius and h is the height.

• Volume = 4/3πr³, where r is the radius.

If a cylinder has a radius of 3 m and a height of 5 m, what is its volume?

• 30π m³

• 45π m³

• 60π m³

• 75π m³

What is the formula for the volume of a sphere?

• Volume = (4/3)πr³, where r is the radius.

• Volume = 2πr², where r is the radius.

• Volume = πr²h, where r is the radius and h is the height.

• Volume = (1/3)πr²h, where r is the radius and h is the height.

A cylinder has a height of 10 cm and a diameter of 6 cm. What is its volume?

• 60π cm³

• 90π cm³

• 5 cm

• 10 cm

• 15 cm

• 20 cm

What is the formula for the volume of a cone?

• Volume = (1/3)πr²h, where r is the radius and h is the height.

• Volume = πr²h, where r is the radius and h is the height.

• Volume = (2/3)πr²h, where r is the radius and h is the height.

• Volume = (1/4)πr²h, where r is the radius and h is the height.

What is the volume of a cylinder with a radius of 2 cm and a height of 6 cm?

• 12π cm³

• 24π cm³

How do you convert the diameter of a sphere to its radius?

• Radius = Diameter / 2

• Radius = Diameter x 2

• Radius = Diameter + 2

• Radius = Diameter - 2
