2. Circumference
• The circumference is the total distance around the circle. The value of
the circumference can be obtained by multiplying the diameter by pi
(𝜋= 3.1416).
We can solve for the circumference of a circle using its radius and
diameter.
In symbols,
C = 2𝜋r ; C = 𝜋d

5. Area of a Circle
▫ The area of a circle is the total measure of the space bounded by
circumference. It can be obtained by having pi times the square of the
radius.
In symbols we have,
A = 𝜋r2
