Answer:36π squared feet
Step-by-step explanation:
Diameter=12
Radius=diameter/2
Radius=12/2
Radius=6 feet
Area of circle=π x Radius x Radius
Area of circle=π x 6 x 6
Area of circle=36π
Equations are: 4x + 2y = 6
x - y = 3
Multiply 2nd equation by 2,
2x - 2y = 6
Add both the equations,
6x = 12
x = 12/6
x = 2
In short, Your Answer would be 2
Hope this helps!

➷ As the two lengths are a, this means it is an isosceles triangle.
The two unknown angles would be equal so we can calculate them:
(angles in a triangle equal 180 degrees)
(180 - 90) / 2 = 45
Now we can use the sine rule to calculate the length a
(6 / sin(90)) x sin(45) = a
a = 4.242640687
To one decimal place, your answer would be:
a = 4.2mm
