A round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the centre) having Length made the Round Bar.
Radius (R) = Diameter(D) / 2
Diameter (D) = 6 m
Radius (R) = 6 / 2 = 3
Height (H) = 10 m , Area (A) = ?
Area (A) = 2*π*32 + (2*π*3*10)
Area (A) = π * ( 18 + 60 ) = 78*π
Area (A) = 245.0442 m2
