Question

Explain each step in the process of finding the area of a circle given the circumference

Answer 1

Answer:

Substitute the known circumference into the formula C = πd. Divide by π to find the diameter. Then divide the diameter in half to find the radius. Substitute the radius into the area formula, A = πr2. Square the radius and multiply by π to get the area.

Step-by-step explanation:

Answer 2

Area=pi*radius squared (A=pi*r^2)
Circumference =2*pi*radius (C=2*pi*r)

So, if you know C, plug it in and solve for r.
Then plug r into 1st equation to get A.
