Question

You might need: Find the area of a circle with a circumference of 12.56 units.​

Answer 1

The area is 12.56 units^2 (same as circumference?)

Explanation:

Assuming pi is 3.14, the equation for the circumference is C = 2 pi r

Fill it out for the radius (r)

12.56 = 2 3.14 r

12.56 = 6.28 r

r = 2

With the radius, the equation for the area is A = pi r^2

Fill it out for the area

A = 3.14 2^2

A = 3.14 4

A = 12.56
