A circle has a center at (5, 5) and a radius of 2. If the format of the equation for the circle is (x − h)2 + (y − k)2 = r2, then what is r2?

Select one:
A. 1
B. 2
C. 3
D. 4
E. 5

D:  r^2 = 4

Step-by-step explanation:

Square the radius:  r^2 = 2^2 = 4 (answer)

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
