Volume of cylinders practice pre algebra unit 7 lesson 5
To find the volume of a cylinder, you can use the formula V = πr^2h, where V represents the volume, r represents the radius, and h represents the height of the cylinder. Here are some practice problems for calculating the volume of cylinders:
1. Find the volume of a cylinder with a radius of 4 inches and a height of 10 inches.
V = π(4^2)(10) = 160π cubic inches
2. What is the volume of a cylinder with a radius of 5 centimeters and a height of 8 centimeters?
V = π(5^2)(8) = 200π cubic centimeters
3. Calculate the volume of a cylinder with a radius of 6 meters and a height of 3 meters.
V = π(6^2)(3) = 108π cubic meters
4. Determine the volume of a cylinder with a radius of 2.5 inches and a height of 12 inches.
V = π(2.5^2)(12) = 90π cubic inches
5. Find the volume of a cylinder with a radius of 9 centimeters and a height of 15 centimeters.
V = π(9^2)(15) = 1215π cubic centimeters
Remember to square the radius before multiplying by height, and use π as an approximation of 3.14 (or use your calculator's π button).
