The area of the circle above is 1,808.64 units. what is the circumference of the circle? use = 3.14.
a. 150.72 units
b. 75.36 units
c. 602.88 units
d. 904.32 units

To solve for this, we need to understand the formula for the area of a circle, and the formula for the circumference of a circle.
Area =
Circumference = 2R

Since we have the area, 1,808.64 units, we need to divide by 3.14 () first so we can square root (as we are doing the opposite of the formula) the quotient.

1,808.64 / 3.14 = 576

Square root 576.
= 24
24 is our radius.

Now that we've broken it down, let's look for the circumference.

Remember, our formula for the circumference is 2R.

2 x 24 x 3.14
48 x 3.14
150.72 is your circumference.

Your answer is A.) 150.72 units.

I hope this helps!
