Find the equation of the circle if one of the endpoints of the diameter is (-2,-3) and the midpoint of the circle's diameter is (4,5).

The answer to your question is    (x - 4)² + (y - 5)² = 100

Step-by-step explanation:

Data

Point = (-2, -3)

Midpoint = (4, 5)

Process

1.- Find the length of the radius using the formula of the distance between two points.

dPM =

x1 = -2   y1 = -3   x2 = 4   y2 = 5

dPM =

dPM =

dPM =

dPM =

dPM = 10

2.- Find the equation of the line

                  (x - h)² + (y - k)² = r²

h = 4

k = 5

r = 10

                 (x - 4)² + (y - 5)² = 10²

                 (x - 4)² + (y - 5)² = 100

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
