How do you derive the pi value using integral?
For example, by calculating the surface of a circle, using an integral.
Derive the expression for ripple factor of pi filter?
ripple factor:=21/2 /3 *Xc/XL
Derive the formula for radius if the formula is c equals pi times r squared?
Where pi (~ 3.1416) is represented by π, The formula C= πr2 yields the formula r2 = (C/π) therefore r = square root (C/π). ...which is the same as : r = (C/π)1/2.
Use derive in a sentence?
I derive that this question needs to be moved.
What is the approximate volume of a cylinder if the cylinder is 13 feet tall with a circumference of 4.5 feet?
The way I remember the equation for the volume of a cylinder is by thinking of it as a circle with height. The area of a circle is pi x r^2, so the volume of a cylinder is pi x r^2 x h. We need to derive r from the circumference. Since pi is the ratio of any circle's circumference to its diameter, just divide the circumference by pi to get the diameter, then divide that by 2 to get the radius. So the radius is (2.25/pi) ft. When we square that, we have (5.0625/pi^2) ft^2. Multiplying that by pi gives us (5.0625/pi) ft^2. Multiplying by the height makes it (65.8125/pi) ft^3, which is roughly 21 cubic feet.HAPPY PI DAY on 3/14! Better yet, HAPPY PI MINUTE at 3/14/15 9:27!
