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
1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!
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).
Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units
2(pi r square)+(2 pi r)*h
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in 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
the defnition of find the surface area of triangular prism and cylinder
im not 100% sure but i think you multiply length times width
Surface Area: 2πr2 + 2πrh Volume: πr2h
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.
