of a circle to any point on its outer circumference,
which is half the diameter.
The area of a circle is worked out by multiplying π
(Pi – 3.142) by the radius squared: Area = πr

.
And just a reminder that a number is squared if it
is multiplied by itself, and is represented by a
2
.
For example 5 x 5 = 5

Area = 2 m x 2 m (radius) x 3.142 = 12.568 m

or another way of writing it is:
Area = 2

m x 3.142 = 12.568 m
