Volume of right circular cilinder
πr²h
The formula for the volume of a right circular cylinder is:
V = πr²h
Where V is the volume, r is the radius of the circular base, and h is the height of the cylinder.
To find the volume of a right circular cylinder, you need to know the values of r and h.
The radius is the distance from the center of the circular base to any point on the edge of the circle. You can measure the radius using a ruler or tape measure, or you can calculate it if you know the diameter of the circle. The radius is half the diameter, so if you know the diameter, you can divide it by 2 to find the radius.
The height is the distance between the top and bottom of the cylinder. You can measure the height using a ruler or tape measure.
Once you have the values for r and h, you can insert them into the formula and calculate the volume of the cylinder. Remember to use the value of π as approximately 3.14.
Here’s an example:
If the radius of a cylinder is 5 cm and the height is 10 cm, then the volume would be:
V = πr²h
V = 3.14 x 5² x 10
V = 3.14 x 25 x 10
V = 785 cubic centimeters
So the volume of the cylinder is 785 cubic centimeters.
