Answer:
D. 220.16 Square feet
Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is 
. So we fill in this equation with the information we already know:
Simplify the exponents
Multiply
So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple 
which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.
1024-803.94= 220.16 square feet
Answer:
The perimeter of the kitchen wall = 60 b
Step-by-step explanation:
The number if tiles used in the length side of the square walk = 5 tiles
The length of 1 tiles = 3 b
So, the length of 5 tiles = 5 x ( Length of 1 tile)
= 5 x (3 b) = 15 b
So, the length of the square walk = 1 5 b
Perimeter of SQUARE = 4 x SIDES
⇒ Perimeter of the wall = 4 x (Side)
= 4 x (15 b) = 60 b
Hence, the perimeter of the kitchen wall = 60 b

Answer:
approx. 24.6 ft
Step-by-step explanation:
x=the distance of the fire from the base of the tower
200ft=the height of the tower
7 degrees=the angle of depression
Using these values you can draw a diagram that highlights that you need to use trig. to work out the answer.
Using Tan:
Tan 7=x/200 ft
multiply both sides by 200 ft
200*tan 7=24.55691218
approx. 24.6 ft
