Question

The diameter of a circle has endpoints (-3, 2) and (3, -2) which is closest to the length of the diameter of the circle?

Answer 1

D=√((x2-x1)²+(y2-y1)²)

D=√((x2-x1)²+(y2-y1)²) = √(3-(-3))²+(-2-2)²) = √(6² + 4²)=√(36+16)=√52
D=2√13≈7.21

Answer 2

`\text{Diameter = } √((2+ 2)^2+ (-3-3)^2 ) = √(16 + 36) = √(52) = 7.21 \text{ units}`

Answer: Diameter = 7.21 units
