What does 2pi equal?
Let pi=3.14 So: 2(3.14) -> 2(3.14)=6.28 Therefore: 2pi=6.28
What is the area of a circle if the radius is 4.2 rounded to 2 DP?
Area of a circle = 2pi*r2 = 2pi*(4.2)2 = 110.84
What is 2pi r?
it is the formula of circumference of circle
Formula of r form c equals 2pi r?
The circumference of a circle C is 2Pixr So solving for r we have C/2Pi=r
What is 70 degrees in radians?
To convert degrees to radians, you need to multiply the degree measure by 2pi/360Multiply 70 by 2pi/360 and you get approximately 1.22173047.
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
Is 2pi rational?
NO. pi is an irrational number, therefore, 2pi is also an irrational number/
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)
