Concrete pipe

How much will cost cover a 6 m long concrete pipe with an outer radius 1.5 m and inner radius 0.8 meters if 1 m2 paint costs 24 €.

Result

x =  2323.77 Eur

Solution:

x=24⋅ 2π⋅ (6⋅ (1.5+0.8)+1.52−0.82)=2323.77  Eur x=24 \cdot \ 2 \pi \cdot \ (6 \cdot \ (1.5+0.8)+1.5^{ 2 }-0.8^{ 2 }) = 2323.77 \ \text{ Eur }
