Answer:
13.04 cm^2
Step-by-step explanation:
Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm
The Area of a circle is A = πr^2 = πd^2/4
Larger Circle divide the diameter by 2 = 6.25 cm
Smaller Circle dive the diameter by 2 = 1.75 cm
Using above formula A = 122.71846303085 cm^2 &
Finally we deduct the smaller Area from the larger Area
A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2
122.71846303085 cm^2 - 9.6211275016187 cm^2 =
113.0973355292 cm^2 thus 13.04 is your answer since I used the
π = 3.1415926535898
A = area
π = pi = 3.1415926535898

Step-by-step explanation:
Answer:
$455.84
Step-by-step explanation:
find area of the two halves of the circle and the rectangle
area of circle= 
where r= 2 ft
therefore
area of rectangle= 
where w= 4ft and l= 5ft
therefore
add areas together
it costs $14 per square foot and there are 32.566 square feet, so multiply
