Answer:
If the circle's radius is 3, then its area is 28.27 cm.
Explanation:
A circle's area is equal to (A = π r²).
Plug in the radius for R, and your equation should look like the following:
A = π3²
According to PEMDAS, you have to do the exponent first.
Do 3 squared, THEN multiply what you get by pi.
Then what you get should be your area.
