Oh, what a delightful question! To find the volume of a cylinder, you can use the formula V = πr^2h, where r is the radius and h is the height. Plugging in the values, we get V = π(8 cm)^2(20 cm) = 1280π cm^3. So, the volume of the cylinder is 1280π cubic centimeters. Isn't that just lovely?

How do you find volume of a metal cylinder?

You will need to know the height and diameter of the cylinder. Then multiply pi (3.14159) by the square of the radius (r= exactly half of the diameter) , and then multiply that by the height.V = πr²hExample: The cylinder is 12 inches in diameter, and 20 inches tallV= (3.14159 × 6²) × 20(3.14159 × 36) × 20113.097 × 20 = 2261.94 in³


The radii of two circular cylinders are in the ratio 2 3 and their height are in ratio 5 4 calculate the ratio of their volumes?

Let the radius of the first be 2r; then the radius of the second is 3r Let the height of the first be 5h; then the height of the second is 4h volume cylinder = π × radius² × height → volume first = π × (2r)² × 5h = 20πr²h → volume second = π × (3r)² × 4h = 36πr²h → ratio of their volumes is: 20πr²h : 36πr²h = 20 : 36 (divide by πr²h) = 5 : 9 (divide by 4)
