We begin the calculations right away :
Given that the total cost of painting = 2200
The cost of painting = 20 per m²
The curved surface area will be :
2200/20 = 110 m²
The formula for getting the curved surface area is :
Area = 2πrh
Where π = 22/7
H = 10
Therefore :
110 = 22/7 × 2 × r × 10
110 = 440r/7
770 = 440r
r = 770/440 = 1.75m
So :
a) 110m²
b) 1.75m
c) the man has employed children which is a form of child abuse.
