Question
What is the equation of a circle centered at the origin with radius 13?A.x3 + y3 = 169B.x3 + y3 = 13C.x2 + y2 = 13D.x2 + y2 = 169SUBMITarrow_backPREVIOUS
Solution
The equation of a circle centered at the origin with radius r is given by the formula x² + y² = r². In this case, the radius is 13, so when we substitute r with 13 in the formula, we get x² + y² = 13². Therefore, the correct answer is D. x² + y² = 169.
