Question

If the circumference of a circle is 50 , calculate the area of the circle.

Answer 1

Example: you need to find the diameter from the circumference information given:
The circumference of a circle is 15.7 centimeters. What is the diameter?
Solution: C equals Pi times d
15.7 cm = 3.14 · d
15.7 cm ÷ 3.14 = d
d = 15.7 cm ÷ 3.14
d = 5 cm

So 1/2 the diameter is the radius so find the area is pi radius squared ie: pi x (r x r)
