#### What is the formula for volume of cones?

The formula for the volume of a cone is V = pr2h3, where V is the volume in cubic units, p is a mathematical constant called pi and h is the height of the cone. It is used to calculate the volume of a conical shape when the base radius, diameter, height, and slant height are known.

A circular base is a point in space that is surrounded by a lateral surface area or curved surface area that wraps around the circular base forming a cone. This surface area is called the lateral surface, and the surface area of the circular base is called the circular surface.

There are a few ways to find out the surface area of the base of a cone, but it is easiest if you know the diameter of the circle. If you do not know the diameter, you can use a ruler to measure the widest pie circular base and divide that number by 2p to get the radius.

You can also calculate the area of a circular base using a Pythagorean Theorem by determining the hypotenuse length and dividing it by half the height, which is the slant height. You can do this with a ruler or with a calculator and you can even write it down if you have the right measurement!

#### What is the formula for volume of cylinders?

The volume of a cylinder is exactly one third of the volume of a conical shape with the same base, because they come to a point. This is the same relationship that holds for calculating the volume of a pyramid and a sphere, except that they don’t come to a point.

It is important to remember that the volume of a cylinder, as with all shapes, has two dimensions, width and length. It can be useful to know the formula for calculating the volume of a cylinder and the equations for calculating the volume of pyramids and spheres, because they are so often connected.

Calculating the volume of a cone is easier if you know the base area of the cone and the slant height of the cone, or the volume of a cylinder, which is a third of the volume of the pyramid or sphere. It is a simple matter of multiplying the base area of the cone and the corresponding slant height by p, a mathematical constant.

A slant height is the distance from the vertex of the cone to the center of the base. The slant height is usually found by dividing the height of the cone by the radius of the base, but if this is not possible you can use a Pythagorean Theorem to determine the slant height.

When calculating the volume of a pyramid or sphere, you need to multiply the area by the radius of the circle, or in other words, the square unit of the shape. This is a very simple formula that will be used all the time, but it can be difficult to remember when you are calculating the volume of an irregular solid.
