Answer: ![5027.2\ ft^2](https://tex.z-dn.net/?f=5027.2%5C%20ft%5E2)
Step-by-step explanation:
Given
The radius of the circle is ![r=40\ ft](https://tex.z-dn.net/?f=r%3D40%5C%20ft)
The area of the circle is given by ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Insert the value of radius and get the area to play
![\Rightarrow \text{Area A=}\pi \times 40^2\\\\\Rightarrow A=3.142\times 1600\Rightarrow A=5027.2\ ft^2](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctext%7BArea%20A%3D%7D%5Cpi%20%5Ctimes%2040%5E2%5C%5C%5C%5C%5CRightarrow%20A%3D3.142%5Ctimes%201600%5CRightarrow%20A%3D5027.2%5C%20ft%5E2)
Thus, the area to play is ![5027.2\ ft^2](https://tex.z-dn.net/?f=5027.2%5C%20ft%5E2)
Let the variable be x
A number isn’t given so pick any number.
Let’s use 10
Set up the equation to get:
X + 10 = -8
Solve for the variable by subtracting 10 from both sides:
X = -18
Let the variable be y and pick any number, let’s use the number 2.
Equation: 2 x y = 4/5
Solve for y by dividing both sides by 2:
Y = 2/5
