What is the radius of a circle if the circumference is 244.92?
Circumf. divided by 2Pi = radius 244.92 / 2Pi = 38.98 radius (to nearest hundredth).
Convert 16.75 radians to revolutions?
One revolution = 2Pi radians 16.75 radians / 2Pi radians/rev ~= 2.666 revolutions
What is the radius of a circle with a circumference of 26.69 meters?
Circumference = 2pi*r 26.69/2pi = 4.248m (rounded to three decimal places)
What is the circumference of a circle when the area is 36 pi?
To convert area into circumference, take the two formulas for circles--circumference and area: C=2pi*r A=pi*r^2 Now, isolate the common variable (r) in the second equation. r=sqrt(A/pi) Now you can substitute this in for "r" in the first equation to find circumference C=2pi*sqrt(A/pi) C=2pi*sqrt(36pi/pi) pi cancels out C=2pi*sqrt(36) C=2pi*6 C=12pi
Is 12.67 rational or irrational?
It is a rational number
Can the quotient of two irrational numbers be rational?
Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.
Is the quotient of two irrational numbers is irrational?
In general, no. It is possible though. (2pi)/pi is rational. pi2/pi is irrational. The ratio of two rationals numbers is always rational and the ratio of a rational and an irrational is always irrational.
What is the reciprocal of 2pi?
Reciprocal of 2pi = 1/(2pi) = 0.159155(rounded)
Is negative 2pi a rational number?
No. The number pi is irrational, and if you multiply an irrational number by a non-zero rational number (in this case, -2), you will get another irrational number.As a general guideline, most calculations that involve irrational numbers will again give you an irrational number.
Does percents are rational or irrational?
It depends on the percentage. A 1 cm arc of a circle whose radius is 1 cm will represent 100*1/(2pi) % = 50/pi % and that is an irrational percentage. A semicircular arc of the same circle will represent 50%, which is rational.
What is cos 2pi?
The cos of 2pi is 360 degrees which is 1.
What is pi added to pi over two?
(pi^2+2pi)/2pi
What is the circumference of a circle with a 2pi radius?
The circumference of a circle with a 2pi radius is: 39.58
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.
What is the ratio of the circumferences for two circles with areas 6 pi m2 and 150 pi m2?
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)
Is 2Pi r the same as Pi r squared?
No. 2Pi r is equal to Pi d, though.
How do you find the radius if circumference is given?
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
