(h is the height of the cylinder, r is the radius of the top)
Surface Area = Areas of top and bottom +Area of the side
Surface Area = 2(Area of top) + (perimeter of top)* height
Surface Area = 2(pi r 2) + (2 pi r)* h

1/3Ah That is to say, 1/3 times the area of the base times the height (not the slant height) of the cylinder
A cylinder with a 7cm radius and 3cm height has a total surface area of about 439.82cm2
How do you find the suface area of a net? Answer: Do the formula for each shape that is in the net.
Multiply the length of any side by the same number.
Surface area of a sphere = 4 x (pi) x (radius)2
