Worksheet Overview

In this activity, you will asked to complete different questions all about circles.

 

A circle is a 2D shape where every point on a circle has the same fixed distance from the centre.

 

In Year 6, we learn about the parts of a circle.

 

Let's recap:

 

Diameter

This circle shows the diameter. This is the length of the line through the centre, from one edge to the other.

Radius

This circle shows the radius. The radius is the distance from the centre of the circle to the outer edge.

The radius is half of the diameter so is fairly straightforward to calculate.

Circumference

A circle's circumference is the distance around the edge.

Example

If a circle's diameter is 12 cm, what is its radius?

 

Answer

The diameter is double the size of the radius, so the radius is half the size of the diameter!

12 ÷ 2 = 6

The radius is 6 cm.

 

Remember that the diameter is double the radius, so we would need to halve the diameter to get the radius
