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.
The surface area of a cylinder is 2πrh + 2πr². The variable r is the radius and h is the height.2πr² is the area of the top and bottom parts of the cylinder.2πrh is the area of the round circular part.
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.
The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
Surface Area = Pi*radius(radius + slant height)
The height of a cylinder with a radius of 8 and a surface area of 954.56 is 10.99
The surface area is 69.12ft2
Surface Area = 2,387.61 ft2
Surface Area = 2,760.67 ft2

Divided into 3 sections (the rounded middle-section and the two circular ends), the surface afrea is equal to the area of the circular end multiplied by two (which equals pi X the radius of the circle squared) plus the circumference of the circular end multiplied by the length of the cylinder. Therefore total surface area = 2(pi X radius squared) + length(pi X 2 X radius)
The formula for surface area of a cylinder is: 2(pi)r2+2(pi)rh. r= radius h= height.
A cylinder filled with water has properties such as volume, surface area, and weight. The volume of water in the cylinder is determined by its height and radius. The surface area of the cylinder is the total area of its curved surface and two circular bases. The weight of the water in the cylinder is influenced by its volume and density.
Surface Area = Pi*radius(radius + slant height)
The height of a cylinder with the radius of 7 and surface area of 550 is 5.51
The height of a cylinder with a radius of 8 and a surface area of 954.56 is 10.99
