Formula to estimate the amount of material required to cover firm 1's structure not including the floor is; πr² + πrh
From the complete question seen online,
The given parameters are;
The shape of the firm 1's structure = Cylindrical shape
The radius of the firm 1's structure = 35
Height of firm 1 structure = 60
The amount of material to cover the firm 1 structure not including the floor = The surface area of a cylinder excluding the base
The formula for the surface area of a cylinder = 2πr² + πrh
If we take away the area of the base, we have;
Surface area of a cylinder excluding the case = 2πr² + πrh - πr² = πr² + πrh
Formula to estimate the amount of material required to cover firm 1's structure not including the floor = πr² + πrh
