Question

What is the area of a circle with a circumfrerenc of 18.84 unites

Answer 1

Answer: The circumference should be:

A = 28.245 or A = 28.25 ( Rounded to the nearest hundredth if needed).

Step-by-step explanation:

In order to find the area of the circle, you need the equation:

$A= \frac{C^2}{4\pi }$

-With the circumference already been known, the equation would be:

$A = \frac{18.84^2}{4\pi }$

-The, solve it:

$A = \frac{18.84^2}{4\pi }$

$A = \frac{354.9456}{4\pi }$

$A = \frac{22841}{2500\pi } = 28.245$

-Round to the nearest hundredth if needed:

$A = 28.25$
