Question 824731
sounds like you want the surface area (SA) of the tree in feet
SA = (2 * pi * radius^2) + (2 * pi * radius * length)
We have the breadth equal to 12 inches and height equal to 12 inches, therefore the base of the tree is a circle whose radius is 12/2 inches = 6 inches = 0.5 feet
pi = 3.14159
now we can substitute into our SA equation
SA = (2 * 3.14159 * 0.5^2) + (2 * 3.14159 * 0.5 * 6)
SA =  1.570795 + 18.84954 = 20.420335 feet
Tearing cost = 20.420335 * 60 = 1225.2201 = 1225 rupees
