Answer:
3.43
Step-by-step explanation:
To do this you would first find the area of the square which is 16. Then you would find the area of the 2 semicircle or just on whole circle. We are just going to use the formula for a whole circle since there are 2 semicircles. The formula to find a circle is pi times r^2 so we are going to put that into a calculator so we would do pi times 2 (radius of circle)^2 which is 12.57 and we would subtract 16 by 12.57 which is 3.43
Maybe factoring it would be a model

Answer:
А. Зп > 9
Step-by-step explanation:
The inequality of A may or may not be true. (It is true only if n > 3.) All of the others are definitely false.
The paint required to cover 1 door is 5/4 liters.
Step-by-step explanation:
The paint required to cover 1 3/5 doors = 2 liters.
Convert mixed fraction into proper fraction.
Therefore, the paint required to cover 8/5 doors = 2 liters.
The paint required to cover 1 door = x liters.
To find x :
Comparing the given data and the unknown data.
8/5 door / 2 liters = 1 door / x liter
x = 2 × 5/8
x = 10/8
x = 5/4 liters.
The paint required to cover 1 door is 5/4 liters.
