WebJun 15, 2024 · Example 9.18.4. The circumference of the base of a cylinder is 16π and the height is 21. Find the surface area of the cylinder. Solution. We need to solve for the radius, using the circumference. 2πr = 16π r = 8. Now, we can find the surface area. SA = 2π(8)2 + (16π)(21) = 128π + 336π = 464π units2. Example 9.18.5.

WebJan 14, 2024 · r = − 2 π h ± 4 π 2 h 2 + 8 π A 4 π. Since the expression under the radical is greater than 2 π h you choose the "plus" root so that the radius is positive: r = − 2 π h + 4 π 2 h 2 + 8 π A 4 π. But to solve for the numerical value of r given h = 8 inches, you'll need more information. You'll need the surface area also to get the ... WebThe formula for the volume of a cylinder is height x π x (diameter / 2)2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2. Visual in the figure below: First, measure the diameter of the base (usually easier than measuring the radius), then measure the height of the cylinder.
WebAnswer (1 of 45): If you are only given the volume of the cylinder and you want to find the radius, it is a bit of a problem. There are ways of finding it though, but it would require for you knowing just one more value. Depending on what other value you can find determines how you can find the r...
