Answer:
Radius = 5
center is (19,-1)
Step-by-step explanation:
Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.
Distance between the points is calculated using formula
diameter = 10
radius = diameter divide by 2
Radius = 5
midpoint is the center of the circle
(19,-1)
Equation of the circle
h,k is the center and r is the radius
h=19 and k=-1 , r=5

Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:
1/2 • 9 • 3 = 13.5
Since there’s 2 triangles we do:
13.5(2) = 27
Now the rectangle in the middle, where the height is 9cm and the base is 12cm:
12 • 9 = 108
Add up the areas:
108 + 27 = 135
