There are various options for you to select from including having a 1-1 video conference session with a national award-winning teacher.
In a 1-1 session, Patrick will take you through the questions step-by-step and teach you how to answer the questions.
In order to benefit from this worksheet you should have an understanding of how to calculate the area of a circle. In the 1-1 session this can be covered if you are unsure.
During a 1-1 video conference you are not required to be on camera.
Patrick will demonstrate how to answer the questions using an iPad and Apple pencil. Everything can be recorded, if you wish, for future reference.
You will need a calculator to calculate the final answer. The use of a Pi button or simply using Pi = 3.14 will suffice.
It is common practice to use an approximate value for Pi. However, using the Pi button on your calculator will give you a more accurate result.
Once you have learnt how to calculate the area of a circle you will find that you can use the formula for other questions involving semi-circles, quarter circles, and compound shapes.
Some of the latter questions in this worksheet involve part circles, thus helping you to deepen your understanding.
If you need any advice about this worksheet and whether it will suit you then please feel free to make contact.
How to Calculate the Area of a Circle
Calculating the area of a circle involves using the formula Area = pi x radius squared.
Pi is a special number with an approximate value of 3.14. It is defined as the ratio of the circle's circumference to its diameter.
The circumference is the length of the perimeter of the circle and the radius is the straight line distance from the centre to any point on the circumference.
For example, if we have a circle with a radius of 10 cm then we can calculate the area of the circle as follows:
