Best Answer

Notice that if you were to slit the cylinder down the side, unroll it, and lay it flat,

you'd have a rectangle, with one dimension equal to the circumference of the base,

and the other dimension equal to the height of the cylinder.

The surface area is just "rectangle's" (length) x (width) = (2 pi R) x (h) .

Total surface area = (2*pi*radius2)+(diameter*pi*height)

Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units

you divide the surface area by the circumference.

if the cylinder is on the inside, it would not affect the surface area. otherwise, subtract the part of the inside cylinder that touches the outside from the cylinder

Surface Area: 2πr2 + 2πrh Volume: πr2h

Total surface area = (2*pi*radius2)+(diameter*pi*height)

To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).

Unless the context suggests otherwise, the two are the same. However, you may, for example, be required to find the curved surface area of a cylinder and [then] the total surface area. In that case the total surface area would include the areas of the two end faces.
