Question

The circle below is centered at the origin and has a radius of 5. What is itsequation?A. x² +²2² = 5B.x2²-2²= 25C. x²-2²=5D. x² + y² = 25

Answer 1

circle with a radius of 5

circle equation is ax^2 + by^2 = c

for the radius to be 5 c must be 5^2 or 25

so B or D

B has a (-) not a (+) so it actually isn't a circle

D
