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)
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 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 cos 2pi?
The cos of 2pi is 360 degrees which is 1.
What is the circumference of a circle with a 2pi radius?
The circumference of a circle with a 2pi radius is: 39.58
What is pi added to pi over two?
(pi^2+2pi)/2pi
Is 2pi rational?
NO. pi is an irrational number, therefore, 2pi is also an irrational number/
How do you find the circumference of the earth using the arc length formula?
Just did this in my trig class yesterday. Arc length = radius * theta(radians) Circumference of Earth = radius of earth * 2pi Note: The arc length is the circumference of the Earth only in this case because theta is equal to 2pi.
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)
