Right circular cylinder (Self Evaluation) : Class 10 : Mathematics : C-DAC Online Lab

Right circular cylinder

	1)	Cylinder formed by folding a rectangular sheet is a
		Open cylinder Closed cylinder circle cuboid

	2)	Consider a rectangular sheet of length L and breadth B. What will be the radius (R) of cylinder formed after folding sheet by length?
		R = B/π R = L/2π R = B/2π R = L/π

	3)	Surface area of cylinder formed by folding a rectangular sheet is?
		A = 2πrh A = 2πr²h +2πrh A = 2πr²h A = 2π(r+h)

	4)	What will be height of cylinder made by folding rectangular sheet by length?
		Height = (Length)² Height = Breadth Height = (Breadth)² Height = Length

	5)	Circumference of circle is ?
		(Radius)² 2πr πr π
