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
To find the surface area (SA) of a cylinder, you use the formula: SA = 2πr(h + r), where "r" is the radius of the circular bases, and "h" is the height of the cylinder. The formula comprises the area of the two circular bases (2πr²) and the lateral surface area (2πrh). Simply plug in the values for the radius and height to calculate the total surface area.
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
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
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
Total surface area including the two end pieces = (2*pi*radius2)+(2*pi*radius*height) in square units.
the defnition of find the surface area of triangular prism and cylinder
Surface Area: 2πr2 + 2πrh Volume: πr2h
im not 100% sure but i think you multiply length times width
