Radius of circle: 132/2pi = 21cm to the nearest integer
Reciprocal of 2pi = 1/(2pi) = 0.159155(rounded)
The cosine of 2pi is 1. In fact, for every integer N, the cosine of 2 N pi is 1.
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
The cos of 2pi is 360 degrees which is 1.
The circumference of a circle with a 2pi radius is: 39.58
NO. pi is an irrational number, therefore, 2pi is also an irrational number/
Because any angle increased by k*2pi radians (= k*360 degrees) where k is an integer, is, effectively, the same angle. This implies that f(x + 2kpi) = f(x) for any angle x and any trig function f. This gives f a maximum period of 2pi radians.
area = 2pi*r2circumference = 2pi*rThe ratio of their circumferences will be 2pi*r1 /2pi*r2 = r1/r21) r2 = 6pi/2pi = 3. r1 = root(3).2) r = 150pi/2pi = 75. r2 = root(75)So the ratio of their circumferences isr1/r2 = root(3)/root(75)
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
No. 2Pi r is equal to Pi d, though.
Let pi=3.14 So: 2(3.14) -> 2(3.14)=6.28 Therefore: 2pi=6.28
Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).
No it does not have a name.
sec x = 2 cos x = 1/2 x = PI/3 and x=5PI/3 The period of cosine is 2PI The general solutions are: x= PI/3 + 2nPI, where n is any integer x = 5PI/3+2nPI, where n is any integer
One revolution = 2Pi radians 16.75 radians / 2Pi radians/rev ~= 2.666 revolutions
Circumference = 2pi*r 26.69/2pi = 4.248m (rounded to three decimal places)
Area of a circle = 2pi*r2 = 2pi*(4.2)2 = 110.84
Assuming you mean that the pi is not within the sin(2pi), its a vertical shift of +pi
Surface area you mean? Then 2pi*r2 + 2pi*r*h where h=height and r=radius
You can use the circumference of the pencil and the circumference formula to find the radius. Set the measured circumference equal to 2pi*radius and solve. I measured it to about .75 of an inch, so: .75=2pi*radius r=.75/2pi
The speed of a clock hand depends on what the clock hand indicates the second hand is 2pi per 60seconds, the minute hand is 2pi per 3600 seconds and the hour hand is 2pi per 216000 seconds.
the period is 2pi. period is 2pi/b and the formula is y=AsinBx.
it is the formula of circumference of circle
The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
