Question

The diameter of a circle has endpoints whose coordinates are R(-2, 2) and S(4, 2). Find the equation of the circle. (Hint: Review the formula for the equation of a circle.)

(x - ___)^2 + (y - ____)^2 = ___

Answer 1

you can find the coordinates of the centre of the circle by finding the mid point between R and S

Answer 2

and its diameter is the distance between R and S

Answer 3

so it would be 1, 2?

Answer 4

and whats the last blank?

Answer 5

@asnaseer

Answer 6

yes, (1,2) would be the center of the circle

Answer 7

the last blank represents the (radius)^2

Answer 8

you can find the radius as the distance from the center to either R or to S

Answer 9

(x - ___)^2 + (y - ____)^2 = ___ ^2

not
(x - ___)^2 + (y - ____)^2 = ___

right?
