## What does volume of a circle mean?

Like all geometric prisms, a cylinder’s volume is the product of its cross-sectional area and its length. The cross-sectional area is the area of its circle, and you can calculate it from the circle’s radius. Multiply the circle’s radius by 2 to calculate its diameter.

## How do you determine the volume of a circle?

For example, to calculate the volume of a cone with a radius of 5cm and a height of 10cm: The area within a circle = πr2 (where π (pi) is approximately 3.14 and r is the radius of the circle). In this example, area of base (circle) = πr2 = 3.14 × 5 × 5 = 78.5cm2.

**Does a circle have a volume?**

No, a circle doesn’t have a volume. A circle is a two-dimensional shape, it does not have volume. A circle only has an area and perimeter/circumference.

### What is the definition of volume in math?

In math, volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object. Here, for example, the volume of the cuboid or rectangular prism, with unit cubes has been determined in cubic units.

### What is volume of a shape?

Volume is the amount of space a 3D shape takes up. You can work out the volume of a shape by multiplying height × width × depth. If the shape is made of cubic cm blocks, you can count the cubes to find the shape’s volume.

**Where is the radius of a circle?**

The radius of a circle is the length of the line segment from the center of a circle to a point on the circumference of the circle. It is generally abbreviated as ‘r’.

#### What is an example of volume?

Volume is the measure of the capacity that an object holds. For example, if a cup can hold 100 ml of water up to the brim, its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object.
