Answer:
- Option 4
Step-by-step explanation:
Midpoint of the diameter is the center.
<u>Use midpoint formula to determine the coordinates:</u>
- x = (2 - 4)/2 = -1
- y = (5 + 13)/2 = 9
<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>
- r =
<u>Use the equation of the circle:</u>
- (x - (-1))² + (y - 9)² = 5²
- (x + 1)² + (y - 9)² = 25
Correct choice is 4
