The circumference of a cylinder is not dependent on its height, It's simply how far it is round it. So it's the usual formula of 2pi x r. or 3.142 x 2 x 4.25 = 26.707 of the units you have chosen but not mentioned (inches, cms, mms?).
A cylinder with a radius of 11 units and a height of 12 units has a volume of 4,561.59 units3
A cylinder with a radius of 11 units and a height of 12 units has a volume of 4,561.593 cubic units.
The volume of a cylinder with a radius 11 cm and a height of 7 cm is 665.23 cm3
A cylinder that has a radius of 5 inches and a height of 11 inches has a surface area of 502.65 inches2
11*11*3.14*12=4559.28
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
The surface area of a cylinder with a radius of 11 and height of 11 is 1,520.53 units2
The volume of a cylinder 22 height and the diameter of 11 is: 2,090 cubic units.
A cylinder with a radius of 11 units and a height of 12 units has a volume of 4,561.59 units3
A cylinder with a radius of 11 units and a height of 12 units has a volume of 4,561.593 cubic units.
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
The volume of a cylinder with a radius 11 cm and a height of 7 cm is 665.23 cm3
A cylinder that has a radius of 5 inches and a height of 11 inches has a surface area of 502.65 inches2
11*11*3.14*12=4559.28
The typical dimensions of a 2-liter PET bottle are around 11-13 inches in height and 9-10 inches in circumference.
The area is 1,520.53 inches2
The question cannot be answered without more information about the base. Specifically, it is necessary to know whether the base has an area of 11 [square] units, a radius of 11 units, a diameter of 11 units or a circumference of 11 units. "A base of eleven" is next to useless.
