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
Answer: 
Step-by-step explanation:
Area of Rectangle = bh = 16 ft x 18 ft = 288 
Area of Triangle = 1/2 bh = 1/2 x (16-12) ft x (6) ft x 2 (There's 2 triangles) = 24
24 ft^2 + 288 ft^2 = 312 ft^2
0.578=289/500, 3.5= 3 1/2, 2.73= 2 73/100, 0.4211= 4211/10000. Hope this helps :)
The area of the tennis court is computed by multiplying the dimensions given,
A = 120' x 80'
A = 9600 ift
Then, we convert the area in ft² to acres,
A = (9600 in²)(2.3 x 10^-5/ 1 in²)
A = 0.24 acre
The portion of land remaining is,
A of remaining = 0.25 acre - 0.24 acre
= 0.1 acre
The remaining portion is for Andre's studies.
This, 0.1 ft² is equal to the 4% of the given area of the court.
