How does radian measure is related to degree measure?
In radian measure, 2pi radians is a full circle. In degrees, 360° is a full circle, so 2pi radians = 360°. If you want to convert: Radians = (2*pi/360)*Degrees = (pi/180)*degrees. And Degrees = (180/pi)*Radians.
What is the central angle of a circle with a circumference of 9 and arc length of 1?
2pi/9 radians or 40 degrees
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.
How do you convert revolution into radians or degrees?
One revolution = 360 degrees or 2pi radians
How do you work out the circumference of a circle using radius?
The formula for calculating the circumference of a circle is 2πr, where r is the radius of the circle and π is 3.1415926535890793 - usually shorted to either 3.1416 or 3.14 So that the circumference of a circle with a radius of 10 units is 62.83 units There are pi radians in a half of a circle. Thus, the measure of a central angle which is a straight line is pi radians. We have a formula that show that the length of an intercepted arc is equal to the product of the angle in radians that intercepts that arc, with the length of the radius of the circle. So we can say that the length of a semicircle is (pi)(r). In a full circle are 2pi radians. So the length of intercepted arc from a central angle with measure 2pi is 2(pi)(r).
