What is the reciprocal of 2pi?
Reciprocal of 2pi = 1/(2pi) = 0.159155(rounded)
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.
Is 2Pi r the same as Pi r squared?
No. 2Pi r is equal to Pi d, though.
How do you find the angle of a circle divided into 8 equal parts?
There are 2pi in a circle. If we divide a circle into 8 equal parts, then each part will be pi/4, [(2pi)/8].
What is the radius of a pencil?
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
What is the reciprocal of 2pi?
Reciprocal of 2pi = 1/(2pi) = 0.159155(rounded)
When does cosx times sinx times sinx equal 1?
at the angles 0 and 360 degrees, or 0 and 2pi
What is the size of the angle when a revolution is made?
The angle of a full revolution is 360 degrees, which is equal to 2pi radians or 400 gradients.
What is cos 2pi?
The cos of 2pi is 360 degrees which is 1.
What are 2 Objects That Are Equal In Measure?
They are simply two objects which are equal in measure. There is no special word or phrase for them. A circle with radius 2pi and a square with sides of 2pi will have the same perimeter. So they have one measure which is the same but nothing else - other than that they are plane figures. No special name.
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)
