Answer:
A = 981.3 ft^2
Step-by-step explanation:
Here we're calculating the area of a semicircle of radius 25 ft.
The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.
Here pi = 3.14 and r = 25 ft, and so the area/space in question is
A = (1/2)(3.14)(25)^2
A = 981.3 ft^2

Answer:
X=5
Step-by-step explanation:
Multiply by 3 first
The answer is
x = 1 and y = -3
<span>[1] 6x-9=y
[2] y=-3x</span>
The second one same concept 132*70*40=369,600 but you need 3/4 full so 369,600*0.75=277,200 cm^3 of water
So <span>277,200 cm^3 of water is your answer</span>
