The following are the formulas for Area and Volume of cylinder and cone
If you will note the Surface area of Cylinder = 2 x (area of circle- top and base) + surface area of curved (round) section
Area of cylinder = (2 x ∏ x r^2) + (2 x ∏ x r x h) where r is radius of the cylinder, h is the height, ∏ is pi symbol = 3.14…
Volume of cylinder = Area of Circle x Height of Cylinder = ∏ x (r^2) x h
Surface area of cone = Area of Curved section + Area of base circle = ∏ x r^2 +∏x r x l = ∏ x r (r^2 + L) L is length of the curved section
