To calculate the surface area of a cylinder, you need to add the areas of the two bases (top and bottom) and the lateral surface area. The formula for the lateral surface area of a cylinder is 2πrh, where r is the radius and h is the height. Given the radius is 7cm (half of the diameter) and the height is 18cm, the lateral surface area is 2 * π * 7 * 18 = 252π cm². The total surface area is the sum of the lateral surface area and the areas of the two bases, which is 252π + 2(πr²) = 252π + 2(π*7²) = 252π + 98π = 350π cm², or approximately 1099.65 cm².

The curved surface area of a right circlur cylinder of height 14cm is 88 cm find the diameter of the base of the cylinder?
The surface area of a cylinder = height * 2 * pi * radius So, since we know the surface area, and the height, we can rearrange the equation: radius = Surface Area / (height * 2 * pi) = 88/(14 * 2 * pi) = 22/ (7*pi) = approx 1 cm. So the diameter, is 44/ (7*pi) = approx 2 cm.
What is the surface area of a cylinder with diameter 24ft and height 16ft?
The surface area of this cylinder is 2,111.15 square feet.
How do you derive of surface area of cylinder?
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!
What is the lateral surface area of a right cylinder?
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.
What is the surface area of a cylinder if the radius is 3 and the height is 11?
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
