Answer:
Step-by-step explanation:
A = the area of the region outside the semicircle but inside the rectangle
w = the width of the rectangle or diameter of the semicircle
Since "A" is determined by "w", therefore, "A" is a function of "w" = A(w).
A(w) = (area of rectangle) - (area of semicircle)
Where,
lenght of rectangle (l) = w + 5
width of rectangle (w) = w
r = ½*w =
Plug in the values:

The pattern is the number of sides that the shape has. A triangle has 3, the square has 4, the pentagon has 5, then the next shape is a hexagon which has 6 sides, a heptagon has 7, and an octagon has 8. So draw the next three shapes after the pentagon.

I'm going to set this up in a ratio for you. You are going to convert these into regular fractions. So then it becomes
8/48 = 3/x
Then you need to cross multiply. You will do 3*48 divided by 8.
(3*48) = 144
144 divided by 8 is 18.
X = 18
