The circle below is centered at the origin and has a radius of 10. What is its equation?
10
10
O A. x2 + y2 = 100
O B. x2 + y2 = 10
O c. x2 - y2 = 10
O D. x2 - y2 = 100

congruent segments

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
