Question

What is the distance formula used to compute the radius from center (a,b) to a point (x,y)?
Options
A r = √((x-a)² + (y-b)²)
Correct Answer
B r = √((x-a)² + (y-b)²) · 2
C r = (x-a)² + (y-b)²
D r = √((x+a)² + (y+b)²)
Correct Answer

Option A is the correct answer.

Detailed Explanation

The distance formula to compute the radius from center (a,b) to a point (x,y) is r = √((x-a)² + (y-b)²).

Hint

The notes indicate answer B, but that appears to be a typo. The correct formula is A.
