Write the equation of a circle with center upper c left-parenthesis 4 comma negative 5 right-parenthesis that passes through upp
er p left-parenthesis 1 comma negative 2 right-parenthesis number .
1 answer:
The square of the distance between C(4, -5) and P(1, -2) is given by the Pythagorean theorem as
(4-1)² +(-5-(-2))² = 18
This is the square of the radius of the circle, so we can use it for r² in the formula
(x -h)² +(y -k)² = r² . . . . . . . circle of radius r and center (h, k)
Your circle has equation ...
(x -4)² +(y +5)² = 18
(4-1)² +(-5-(-2))² = 18

Answer:
2102.13 mm^2
Attached is a completed image of the question
Step-by-step explanation:
Given;
Radius of the circle r = KL = 27.1 mm
Angle of unshaded region = 32°
The total angle in a circle is 360°
Angle of shaded region θ = 360° - angle of unshaded region.
θ = 360° - 32° = 328°
The Area of a circle = πr^2
Area of shaded region A = (θ/360)πr^2
Substituting the given values;
A = (328/360)×π × 27.1^2
Area of shaded region A = 2102.13 mm^2
