what is the area of a circle with a circumference of 18.84 units .

Answer 1

The area of a circle is calculated by multiplying pi by the radius to the second power (assume pi = 3.14).

A= 3.14 * r^2

Since you are only given the circumference, we can determine the radius using the circumference (C):

C = 3.14 * 2 * r

18.84 = 3.14 * 2 * r

18.84 = 6.28 * r

3 units = r

The radius is 3 units.

Now we can find the area:

A = 3.14 * r^2

A = 3.14 * 3^2

A = 3.14 * 9

A =28.26 square units
