The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
Circumference equals pi multiplied by diameter. Therefore 120 (circumference) divided by pi equals diameter. Pi is on your calculator.
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
No; circumference divided by diameter equals pi.
The circumference of a circle equals pi times the diameter.
The width times pi equals the circumference.
Imagine the cylinder is a stack of thin plates with radius 3. The surface area of the cylinder will be the total of the circumferences (the distance around the outside) of all the plates.First, you need to figure out the circumference of a plate. Circumference equals pi (3.1415926...) times the diameter. (You can probably round pi to four digits for this problem.) The formulas in this specific case are:Circumference = pi multiplied by the diameter (3+3)Surface area = Circumference multiplied by the height of the cylinder (8)The problem doesn't indicate if the cylinder is hollow, so you may need to add the areas of the top and bottom to get the total surface area. The formula for the area of a circle is pitimes the radius squared (3x3).
First we have to find the radius and this is done by the dividing circumference by 2*pi and this works out as 5.092958179 Volume of a cylinder = pi*radius2*height Volume = 692.6423124 or 693 cubic units to the nearest unit
A cylinder has 2 circular ends and the curved side. If the cylinder was a drinks can, then it could be cut down from one ciircular end to the other and the side uncurled to give a rectangle with one dimension the height of the cylinder and the other the circumference of the circular end. Thus the surface area of a cylinder is twice the area of an end plus the circumference of the end times the height of the cylinder: area = 2{pi}r2 + 2{pi}rh = 2{pi}r(r + h) = 2{pi}6(6 + 30) = 12{pi}36 = 432{pi} ~= 1357.2 cm2
The surface area of a cylinder where height is 80cm and radius is 15cm equals 8953.54cm2
The surface area of a cylinder with a height of 18 and a radius of 10 equals 1,759.3 units2
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.

The surface area of a cylinder with a radius of 6 and a height of 7 equals 490.09 square units. (rounded).
The lateral surface area of a cylinder is the area of a rectangle. In other words: when a cylinder is unravelled, you are left with a simple rectangle with width and length. Depending on what kind of cylinder you happen to have, the circumference of the cylinder could be the width or the length. Where you have a short cylinder with a wide mouth, the circumference would become the length and the h would become the w. So, think of a cylinder as a rectangle. Take a piece of paper (rectangular) and bring the ends together. What do you have?: a cylinder. Now - for the formula: Diameter= D, Circumference= C, pi= 3.14 These are the parameters of a circle. Now, in mathematics, the radius of the circle and 2 *Pi is used in order to find the circumference of the circle. So, (D * pi)= 2Pi *r = C Therefore, the circumference or perimeter equals the width and the height or h = length of a rectangle. Now, then: The Formula for the Lateral surface of a cylinder Is: (2*Pi*r)*h= A Remember that the radius is half the Diameter of a circle and must be multiplied by two in order to convert back to D or Diameter. Please, note that ( 2*pi )= 360 degrees, and that it (2*Pi) also represents one whole revolution around the perimeter of a circle. To simplify: Diameter X (3.14) X height = Lateral Area of a cylinder. I hope this is of some help!
The circumference of a cirlce can be found if you know either the diameter (the longest distance from on side on the circle to another) or th radius (half of the diameter). If you know the radius, multiply it by 2 to find the diameter. The cricumference = pi x D This means you times the diameter by pi (3.1415926535...)
2 times pi times the radius squared plus 2 times pi times the radius times the height equals surface area of a cylinder :]
