Volume of Cylinders, Cones, & Spheres 8.7A

What is the formula for the volume of a cone?

• V = πr²h

• V = (1/3)πr²h

• V = (2/3)πr²h

• V = πr²h/2

If a cone has a radius of 4 inches and a height of 9 inches, what is its volume?

• 120.5 in³

• 150.8 in³

• 180.0 in³

• 200.0 in³

If a cylinder has a radius of 5 inches and a height of 10 inches, what is its volume?

• 500 in³

• 785.4 in³

• 314.2 in³

• 1000 in³

What is the volume of a sphere with a diameter of 10 inches?

• 314.2 in³

• 523.6 in³

• 785.4 in³

• 418.9 in³

What is the formula for the volume of a sphere?

• V = (4/3)πr³

• V = πr²h

• V = 2/3πr³

• V = 4πr²

What is the relationship between the radius and diameter of a sphere?

• The diameter of a sphere is equal to the radius.

• The diameter of a sphere is half the radius.

• The diameter of a sphere is twice the radius. d = 2r.

• The diameter of a sphere is three times the radius.

What is the formula for the volume of a cylinder?

• V = πr²h

• V = 2πrh

• V = πr² + h

• V = πd²h

How do you convert diameter to radius?

• The radius r is equal to the diameter d.

• The radius r is half of the diameter d. So, r = d/2.

• The radius r is double the diameter d.

• The radius r is the same as the diameter d.

• 4 cm

• 5 cm

• 6 cm

• 7 cm
