This is how you would set it up
42 47
----- -----
100 x
Then, cross multiply. You should get this:
42x = 4700
Then, solve that problem
42x = 4700
----- -------
42 42
x = 111 < (the answer turns out as a decimal but you should take the whole number)
Then subtract 111 and 100
111 - 100 = 11
Answer - 11%
Hope this helps!
The area of the shaded region is 502.4 sq. ft.
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure. The word "area" refers to a free space.
According to the question,
Diameter of inner circle = 36 ft.
Radius of inner circle = 36/2 ft. =18 ft.
As the width of the ring is 4 ft. , the diameter of the outer circle = 36+4+4= 44 ft.
Radius of outer circle = 22 ft.
Area of the shaded region = Area of outer circle - Area of inner circle
= π(22)(22) - π(18)(18)
= π(484 - 324)
= 3.14 * 160
= 502.4 sq. ft.
