9/20
A percentage is the same as showing a number over 100 and if we multiply 20 by 5 we get 100. So if we multiply 9 by 5 we get 45, giving us 45/100 which can be shown as 45%.
As a decimal, well if we say 100% equals 1.0, then 45% equals 0.45
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
