Total area of closed cylinder = (2*pi* (r^2)) + (2*pi* r * h)
= 74800 cm sq
= 7.48 m sq
Area required from the sheet = 7.48 m sq.
Area left = area of sheet - area required for cylinder
= 0.52 m sq
= 74800 cm sq
= 7.48 m sq
Area required from the sheet = 7.48 m sq.
Area left = area of sheet - area required for cylinder
= 0.52 m sq
