# Volume of Cone and Cylinder Worksheet (with answer key + PDF)

The area or capacity of a cone is determined by its volume. A cone’s circular base tapers from a flat base to a point known as the apex or vertex in three dimensions. The density of a cylinder is determined by its volume, which represents how much material can be immersed in it or carried inside of it. The formula r2h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder.

## What is the volume of cylinders and cones?

A cylinder’s volume is determined by how many unit cubes (cubes of the same length) can fit inside of it. It is the area the cylinder takes up, just as any three-dimensional shape’s volume is the area it occupies. The area or volume that a cone takes up is referred to as its volume.

## Volume of Cone and Cylinder Worksheet (with answer key + PDF)

A cylinder is a solid shape with straight, parallel sides and a circular or oval base or cross-section. It has two circular bases joined by a curved surface and is a closed solid figure. A cylinder can be thought of as a limiting case of a prism.

The Volume of Cylinder Formula

V = A × h, where

• A = area of the base
• h = height

The volume of a Right Circular Cylinder

V = πr2h

Here,

• ‘r’ is the radius of the base (circle) of the cylinder
• ‘h’ is the height of the cylinder
• π is a constant whose value is either 22/7 (or) 3.142

The volume of an Oblique Cylinder

V = πr2h

• the volume (V) of an oblique cylinder whose base radius is ‘r’ and whose height is ‘h’.

The volume of an Elliptic Cylinder

V = πabh

Here,

• ‘a’ and ‘b’ are the radii of the base (ellipse) of the cylinder.
• ‘h’ is the height of the cylinder.
• π is a constant whose value is either 22/7 (or) 3.142.

Volume of a Right Circular Hollow Cylinder

V = π (R2 – r2) h

Here,

• ‘R’ is the base radius of the outside cylinder.
• ‘r’ is the base radius of the inside cylinder.
• ‘h’ is the height of the cylinder.
• π is a constant whose value is either 22/7 (or) 3.142.

Example of Volume Cylinder

A circle has an area of πr2. So, the formula for the volume of a cylinder is πr2h. Amari’s cake is a cylinder with a diameter of 44 cm and a height of 50 cm. What is the volume of the cake? The radius is half the diameter, so the radius is 22 cm.

A cone is a strong, circular, three-dimensional shape. It has a surface that is curved. The perpendicular height is the distance from the base to the vertex. A cone can be categorized as either an oblique cone or a right circular cone. In contrast to an oblique cone, which has a vertex that is not vertically above the base center, the right circular cone has a vertex that is vertically above the center of the base. The volume of a cone is defined as the amount of space or capacity a cone occupies. The volume of the cone is measured in cubic units like cm3, m3, in3, etc.

The volume of Cone Formula

V = (1/3) πr2h

• If the radius of the base of the cone is “r” and the height of the cone is “h”

Volume of Cone with Height and Radius

V = (1/3) πr2h cubic units

Volume of Cone with Height and Diameter

V = (1/12) πd2h cubic units

The Volume of Cone with Slant Height

We know, h2 + r2 = L2
⇒ h = √ (L2 – r2)
where,

• h is the height of the cone,
• r is the radius of the base, and,
• L is the slant height of the cone

V = (1/3) πr2h = (1/3) πr2√ (L2 – r2).

Example of Volume Cone

The volume of space that a sphere can occupy is measured by its volume. If we take a circular disc, attach a string to its circumference, and rotate it along the string, we can draw a circle on a piece of paper. This gives us a sphere-like shape.

The volume of Cylinder = Volume of Cone + Volume of Sphere

⇒ Volume of Sphere = Volume of Cylinder – Volume of Cone
As we know, the volume of the cylinder = πr2h, and the volume of the cone = one-third of the volume of the cylinder = (1/3) πr2h
The volume of the Sphere = Volume of Cylinder – Volume of Cone

⇒ Volume of Sphere = πr2h – (1/3) πr2h = (2/3) πr2h
In this case, the height of cylinder = diameter of sphere = 2r
Hence, the volume of the sphere is (2/3) πr2h = (2/3) πr2(2r) = (4/3) πr3
