What is the formula for calculating total surface area of a cylinder?

A cylinder has two circular ends, then the long side surface, which is actually a rectangle if you flatten it out. You need the radius of the circular end (distance from the middle to the edge), and the height of the cylinder to work out the surface area. Doing the circular ends first, the surface area is given by the formula PI x radius squared. PI is 3.1415 for normal use. There are two ends, so count the answer twice. The side surface is a rectangle with one side of the height of the cylinder, and the other side the circumference of the circular end. The circular end length is 2 x PI x radius of the circular end. Now multiple that answer by the height of the cylinder. Finally add together the area of the two ends (don't forget to count both), and the area of the rectangle making up the long side, nd that's your answer.


What is the surface area of this cylinder that has a radius of 11 inches and a height of 11 inches?

Side Surface area = 2 x Pai x radius x height = 2 x 3.14 x 11 x 11 = 759.88 = 760 SQ inch


How do you find the area of a cylinder?

The total surface area of a cylinder can be found using the formulaA = 2(pi)r2 + 2(pi)rh or A = 2(pi)(r2 + rh)2 (pi x radius squared) = both ends of the cylinderpi x (2 radius) x height = area along the cylinder's side (circumference x height)


How do you calculate the area of a cylinder?

Pi times Radius times Radius times Height.Area of cylinder depends on which side you want.The top and bottom parts = Pi times Radius times Radius. (∩r2)The round part = Pi times Diameter (or 2 * Radius) times Height (∩Dh)Volume = Pi times Radius times Radius times Height (∩r2h)Note: ∩=PiThe area is the outer surface.The surface of a right truncated circular cylinder is calculated as follows:PI * r2 * hwhere PI is the irrational: 3.15158...r is the radiush is the heightIf it is a solid (or a closed shell) then you have to add the ends:twice the area of the circular cross section: PI * r2The volume of a cylinder is equal to Pi times the square of the radius times the height of the cylinder. Pi*r2*h. Pi*r2 is the area of the base of a cylinder. The surface area of a cylinder is 2*Pi*r2+Pi*2r*h. 2*Pi*r2 is the area of the base of the cylinder times two to account for both bases. Pi*2r*h is the circumference of the base times the height of the cylinder


What is the surface are of a cylinder whose radius is 2 and height is 8?

To find the area of a cylinder you need: (π=pi) Therefore the surface area is all of those added together. or simplified Your answer: A=179.4878 Keep in mind that this is the surface area of the top bottom and side, or the total surface area of the geometric object. Be certain the question isn't just being asked of the cylinder wall itself, if that were the case the formula would simply be 2πrh and the answer would then be about 100.5

What is the surface area of a cylinder whose end area is 11 and height is 11 rounded to the nearest whole number?

Imagine taking the ends off the cylinder, cutting the side down from end to end and unrolling the side; this creates a rectangle with the height of the cylinder along one edge and the circumference of the end along the other. Thus area of side = circumference × height. The ends of the cylinder are circles, thus: area = π × radius² → radius = √(area ÷ π) circumference = 2 × π × radius → circumference = 2 × π × √(area ÷ π) = 2 × √(area × π) → area side = 2 × √(area × π) × height → surface area of cylinder = 2 × area ends + area side → surface area = 2 × 11 units² + 2 × √(11 units² × π) × 11 units → surface area = 22 + 22 × √(11π) units² → surface area ≈ 22 + 129.33 units² ≈ 151 units²

Find the height of a cylinder with a radius of 4 centimeter and the surface area is 72pi?

Think of the surface area of the cylinder in three parts. The top, the bottom, and the side. Surface area of the top and the bottom are easy, because the area of a circle is pi times the radius squared. Since the radius is 4, the area of the top and bottom are 16*pi each for a total of 32*pi. This means that the surface area of the "tube part" is 40*pi. {72 - 32 = 40} If you think of cutting this part, you can see that it's really just a rectangle. One side of the rectangle is the height of the cylinder, the other is the circumference of the base. The circumference is 2*pi*r, which here is 8*pi. Thus (8*pi)(height of cylinder) = (40*pi). Conclusion, the height of the cylinder is 5 cm.

If the surface area of a cylinder is 8pei what is the radius?

I guess you mean pi If the radius of a cylinder is "r" and the height is "h" then the total surface area is pi times r times r times 2 (for the two ends) + 2 times pi times r times h (for the side) Your question has two unknowns so can't be solved

What is the surface area of a can?

== == A can is a regular cylinder. It's surface area can be found by finding the area of the ends (finding the area of one end and doubling it) and by finding the area of the side of the can. The ends are circles. The area of a circle is pi times the square of the radius Areacircle = pi x r2 [If you have the diameter of the can, r = d / 2] Find that area and double it. The side surface area of a right cylinder is found by finding the circumference of the cylinder and multiplying by its height. (Think of it as taking the cylinder and cutting it straight up the seam, unrolling the can and finishing the exercise by flattening it out to end up with a rectangle.) Areaside = C x h C = pi x diameter or pi x (2 times the radius) h = Height of can Given the height and the diameter of a can, these ideas can be applied to find its total surface area.
