Determine the volume of a cylinder if it has the following dimensions: r= 7cm and ݄h= 20cm
NOTE: use π= 3,14. Round off to 1 decimal place.
To find the volume of a cylinder, we can use the formula V = π * r^2 * h, where V is the volume, π is a constant (approximately 3.14), r is the radius of the base, and h is the height of the cylinder.
Given that the radius (r) is 7 cm and the height (h) is 20 cm, we can substitute these values into the formula:
V = 3.14 * 7^2 * 20
V = 3.14 * 49 * 20
V = 3080 cm^3
Therefore, the volume of the cylinder is 3080 cm^3.
To determine the volume of a cylinder, you can use the formula:
Volume = π * r^2 * h
Given that the radius (r) is 7 cm and the height (h) is 20 cm, we can substitute these values into the formula:
Volume = 3.14 * (7 cm)^2 * 20 cm
Simplifying this calculation:
Volume = 3.14 * 49 cm^2 * 20 cm
Volume = 3.14 * 980 cm^3
Using a calculator, we can find the result:
Volume ≈ 3068.8 cm^3
When rounded to one decimal place, the volume of the cylinder is approximately 3068.8 cm^3.
