The surface area of a cylinder = 2(pi r 2) + (2 pir)* h, where pi is 3.14159, r is radius, and h is height.
Calculate them and compare.
The surface area of this cylinder is 2,111.15 square feet.
The lateral area of a right cylinder is curved surface that connects the two bases. The surface area is the total area of the curved surface and the bases.Lateral Area: The lateral area of a right cylinder with radius r and height h is L = 2pirh.Surface Area: The surface area of a right cylinder with lateral area L and base area B is S = L + 2B, or S = 2pirh + 2pir^2.
The surface area of a cylinder can be derived from the area of rectangle. If you 'unroll' a cylinder you have a shape of a rectangle, similar to a sheet of paper. The width of the rectangle will be the height of the cylinder and the length of the rectangle will be the circumference of the cylinder end.So, Area = length * widthwhere, width = height of cylinder & length = circumference of cylinder end = PI*(Diameter of cylinder)Therefore,surface area of a cylinder = (PI)*(diameter of cylinder)*(height of cylinder)Hope that helps!
You measure or calculate the surface area; you measure or calculate the volume and then you divide the first by the second. The surface areas and volumes will, obviously, depend on the shape.

Look for the surface area of a cylinder as well as the circles and triangles
Consider it as cylinder..
Calculate them and compare.
Calculate the surface area of the two circles at the ends: TTr2 x 2 = 3.14x7x7=307.72 sq. in. to calculate the surface area of the rectangle that encircles the cylinder, you need the circumference - TTd=3.14*14=43.96 in. LxW= 43.96*4=175.84 sq. in. Add the two together = total surface area of the cylinder = 483.56 sq. in.
2*(r+h)/rh where r is the radius and h the height of the cylinder.
Curved surface area includes the area of the length of the cylinder only whereas surface area includes the two bases as well...
The equation Force = pressure x surface of the cylinder Electric power and torque and power you need to know what you want. After obtaining the surface area of ​​the circle diameter cylinder, the cylinder can get.
face or surface are related words for a surface area of a cylinder
The surface area of the base = Pi x r2 = Pi x 9 cm2 But to calculate the surface area of a cylinder you also need to know its height. The cylindrical surface area will be Pi x 2r x height = (in this case) Pi x 6 x height.
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!
The surface area is 747.7cm2
