If you read about circumferences and pi, you'll no doubt come across circles. In Math, in any circle the ratio of the distance around the curved perimeter to the distance across the circle through the center is the Greek letter π (pi) and has a value of just over 3.

1.
A round table has a diameter of 200 cm. What is the approximate circumference of the table?
286 cm
628 cm
1,256 cm
I need to know the radius first
Using C = 2 π r, 2 x 3.141592 x 100, C = 628.3184 cm. Remember to use radius and not diameter!
2.
A line which passes through the center of a circle and joins two points on its circumference is called a .......
centre line
circumference
diameter
radius
3.
A line which joins the center of a circle to a point on the circumference is called a .......
centre line
diameter
half distance
radius
4.
What is the correct formula for the circumference of a circle?
C = 2πr
C = 2πd
C = 2π
C = 3πr
5.
To the nearest square meter, what is the area of a circular pool with a radius of 10 m?
114 m2
214 m2
314 m2
414 m2
The radius = 10 m, so the calculation is: 3.141592 x 10 x 10 = 314.159 m2
6.
What can be calculated using π r2?
Area of a circle
Circumference of a circle
Diameter of a circle
Volume of a circle
Remember to use the radius of the circle and not the diameter
7.
A circular lawn has a 20 m radius. What is the approximate circumference of the lawn?
100 m
126 m
150 m
175 m
Using C = 2 π r, 2 x 3.141592 x 20, C = 125.66 m
8.
The distance measured around a circle is called the .......
brim
circumference
diameter
radius
9.
What is the area of a circle with a radius of 7 cm (to one decimal place)?
53.9 cm
153.9 cm
315.9 cm
513.9 cm
The radius = 7 cm, so the calculation is: 3.141592 x 7 x 7 = 153.938 cm
10.
The area of a circular lawn is 628 m2. How far is it across to the nearest meter?
20
24
28
32
Remember, you are asked for the diameter not the radius
