Question

The area of a circle is found with the formula A =〖πr〗^2, where π represents 3.14. If a tile artist is placing tiles in a circular mosaic pattern and the area of the circle is 658 square feet, what is the approximate radius of the circle in feet?
a.)10****
b.)13
c.)14
d.)17

Please Check my Answer i really need help on this one i'm so confused

Answer 1

Just looking at the formula, you could surely see that 10 is wrong, because then the area would be 100π = 314, not 658.

So, πr^2 = 658
r^2 = 658/π = 209.4479
r = 14.47

Answer 2

First of all the area of a circle is
π r^2 , not (πr)^2

so πr2= 658
r^2 = 658/π
r = √(658/π) = appr 14.47
