The area of the square is:
And the area of the circle is:
The area of one segment is given by:
Since the point on the 0 is above 20 the y-intercept on your equation has to be above 20. That eliminates A and B. The points trend upward so the slope will have to be positive, that means the answer is C
The Pythagorean theorem tells you ...
... c² = a² + b²
... 13² = 12² + b² . . . . . fill in the given numbers
... 169 - 144 = b² . . . . .subtract 12²
... √25 = b . . . . . . . . . take the square root
... b = 5 . . . . . . The value of b you're looking for.
