Find the surface area of the closed cylinder below to 1 decimal place. The formula for the area of a closed cylinder is:A=2πr(r+h) If we substitute the values of the radius and height into this equation, we get:A=2π(3)(3+8)=2π(3)(11)=2π(33)=66π This gives us a final answer of:A=207.3cm2
Find the surface area of the closed cylinder below to 1 decimal place. The formula for the area of a closed cylinder is:A=2πr(r+h) As the cylinder is lying on its side, the actual 'height' of the cylinder is 6ft and the radius is 1 ½ ft If we substitute the values of the radius and height into this equation, we get:A=2π(112)(112+6)=2π(112)(712)=2π(...
Find the surface area of the closed cylinder below to 2 decimal places. The formula for the area of a closed cylinder is:A=2πr(r+h) We have been given the diameter instead of the radius. To find the radius, we just need to halve the diameter. So the radius of the circular base is:Radius=4.8÷2=2.4m If we substitute the values of the radius and heigh...
Find the surface area of the drinking glass shown below. Give your answer to 1 decimal place. The glass is an open-top cylinder. The formula for the area of a open-top cylinder is:A=πr(r+2h) We have been given the diameter instead of the radius. To find the radius, we just need to halve the diameter. So the radius of the circular base is:Radius=7÷2...
Find the surface area of the relay baton shown below. Give your answer to 1 decimal place. The relay baton is a hollow tube. The formula for the surface area of a tube is:A=2πrh We have been given the diameter instead of the radius. To find the radius, we just need to halve the diameter. So the radius of the circular base is:Radius=112÷2=34inches I...
Learn how to find the surface area of a closed or open cylinder using the formula A = 2 π r ( r + h) or A = π r ( r + 2 h). See worked examples and use the calculator to practice different types of cylinders.
In geometry, the surface area of a cylinder is the amount of space occupied by its surfaces. The surface area of a cylinder is made up of its two bases (grey) and its lateral surface (white), as shown in the figure below. Cylinders are often categorized as right cylinders and oblique cylinders.
Learn how to calculate the surface area of a cylinder using the formula 2πr(h + r), where r is the radius and h is the height. See the derivation, solved problems and practice questions on cylinders.
