Question

What is the area of a circle with a circuference of 12pie

Answer 1

---------------------------------------------
Find Diameter :
---------------------------------------------
Circumference = πD
πD = 12π
D = 12

---------------------------------------------
Find Radius :
---------------------------------------------
Radius = Diameter ÷ 2
Radius = 12 ÷ 2 
Radius = 6

---------------------------------------------
Find Area :
---------------------------------------------
Area = πr²
Area = π(6)²
Area = 36π or 113.10 units² (nearest hundredth)

---------------------------------------------
Answer: Area = 113.10 unit²
