**How do you find the surface area of a ball?**

5/05/2015 · It is observed experimentally that a roughened cylinder or ball will transition to turbulent flow at a lower Reynolds number than a smooth cylinder or ball. Drag for a rough surface ball is shown on the figure at the top of the page by the dashed line. This effect produces a rather interesting result. There is a small range of Reynolds numbers for which the drag of a roughened ball is less... The dodge ball court forms a circle, so we can use the formula to ?nd its area. We know that the radius of the We know that the radius of the circle is 21 feet, so lets put this into the formula and solve for area…
