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.
Pi is irrational.
pi does not exist because pie is round so tell your teacher that pi does not exist
π (pi) = 3.141592653
To convert (3\pi) radians to degrees, you can use the conversion factor (180^\circ/\pi). Multiply (3\pi) by this factor: [ 3\pi \times \frac{180^\circ}{\pi} = 3 \times 180^\circ = 540^\circ. ] Therefore, (3\pi) radians is equivalent to (540^\circ).
To convert radians to degrees, you can use the conversion factor (180^\circ/\pi). Therefore, to convert (3\pi) radians to degrees, you multiply by this factor: [ 3\pi \times \frac{180^\circ}{\pi} = 3 \times 180^\circ = 540^\circ. ] Thus, (3\pi) radians is equal to (540^\circ).
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)
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.
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
To convert degrees to radians, you can use the conversion factor (\frac{\pi \text{ radians}}{180 \text{ degrees}}). For 15 degrees, you multiply by this factor: (15 \times \frac{\pi}{180} = \frac{15\pi}{180} = \frac{\pi}{12}). Thus, 15 degrees is equal to (\frac{\pi}{12}) radians.
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.
The shape factor for a sphere is a dimensionless quantity that characterizes its geometry in relation to its volume and surface area. It is defined as the ratio of the surface area of the sphere to the square of its radius, which is given by the formula ( \text{Shape Factor} = \frac{4\pi r^2}{(2r)^2} = \frac{4\pi r^2}{4r^2} = \pi ). This indicates that the shape factor for a sphere is constant and equal to ( \pi ), reflecting its uniformity in all directions.
ripple factor:=21/2 /3 *Xc/XL
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.
Form factor is (RMS value)/(average absolute value) For sine wave form factor = (1/sqrt(2))/(2/pi) = about 1.11
