Question

What is the circumference of circle P

Leave your answer in pie

Answer 1

14π

Explanation:

The circumference (C) of a circle is calculated using

C = πd ← d is the diameter

here the diameter = AB = 14, hence

C = 14π

Answer 2

Circumference = 2πr = dπ
AB = 14 is the diameter
So circumference is 14π
