What classification of numbers does pi fit into?
pi is infinite pi is about 3.1415
Will the sum of two irrational numbers always be rational?
Consider pi and 4 - pi. 4 - pi + pi = 4, which is clearly rational. However, both pi and 4 - pi are irrational, as you can verify. plz to be lerning numburs Then consider pi + pi = 2pi, which is clearly irrational. The sum of two irrational numbers, therefore, may or may not be rational.
Why is pi a rational number?
Pi is irrational.
What is the exact number for pi?
pi does not exist because pie is round so tell your teacher that pi does not exist
What are the first 10 numbers in pi?
π (pi) = 3.141592653
What is the ratio between radius and area for a circle?
There is no direct ratio. The area is related to the square of the radius by the factor "pi." A = (pi) r2 (Pi is about 3.1416)
If a radius of a sphere increase by a factor of 4 what does the factor of the volume increase?
64The formula to find the volume of a sphere is4/3 * pi * r3where r is the radius of the sphere. So if the radius is increased by a factor of 4, then the formula becomes4/3 * pi * (4r)3 = 4/3 * pi * 64r3showing that the volume increases by a factor of 64.
How do you determine form factor of sine wave?
Form factor of any periodic wave is [RMS CURRENT]/[AVERAGE CURRENT]. For sinusoidal wave RMS current=I/sqrt(2); AVERAGE current=2I/pi; Therefore, Form factor=[I/sqrt(2)]/[2I/pi] =pi/{2*sqrt(2)} =1.11
How do you factor out 4 from pi?
You cannot. pi is an irrational number and the concept of factors really applies only to integers. Once you allow rationals and irrationals, every non-zero number is a factor of every other number. You can divide pi by 4: use a calculator.
Derive the expression for ripple factor of pi filter?
ripple factor:=21/2 /3 *Xc/XL
Why multiply degree to pi by 180 to convert it to radian?
A whole circle is 360 degrees or 2*pi radians. 360 degrees = 2*pi radians so that 1 degree = pi/180 radians This gives the conversion factor of pi/180 to convert degrees to radians.
What is the form factor of sine wave?
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
The transformer utilization factor of full wave bridge rectifier is?
3 phase 3 pulse form factor -> Edc= .675 Eac .675= 3/(pi*sqrt(2)) 3 phase 6 pulse form factor -> Edc = 1.35Eac 1.35= 2*(3/(pi*sqrt(2)))
How are circumference and diameter related?
Circumference and diameter differ by a factor of approximately 3.141, or more precisely, pi. Circumference divided by pi will provide you with the diameter, while diameter multipled by pi will provide you with the circumference. In lieu of a calculator (if you don't have one) that has a pi-function, 3.14 is usually sufficient for an estimate.
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
In the first 1 million digit of pi how many 3 are there?
393 * * * * * Wrong by a factor of 255+ The correct answer is 100,230.
How many times longer is the circumference of a circle than its diameter?
It is larger than the diameter by a factor of Pi (about 3.1416).
