Problem
The radius of a circle is 6 inches. Which choices best represents the circles area?
Use TT= 3.14po
A: 18.84 inches squared
B: 37.68 inches squared
C: 452.16 inches squared
D: 113.04 inches squared
Solution
For this case the are of a circle is given by:
[tex]A=\pi(r^2)[/tex]And since we know that r= 6 inches we can replace and using pi =3.14
[tex]A=3.14(6in^{})^2=113.04in^2[/tex]And the best option would be:
D. 113.03 inches squared
