What kind of angle is 4 pi divided by 5?
pi = 180 degrees pi / 2 = 90 degrees 2 pi = 360 degrees so pi / 5 = 180 / 5 = 36 36 x 4 = 144 degrees a 144 degree angle is obtuse
A circle has radius of 10 cmfind the length of an arc which subtent an angle of 50 degree at the center?
Radius = 10Diameter = 20Circumference = pi D = 20 pi.50 degrees = (50 / 360) of the whole circle.Arc length = (50 / 360) of (20 pi) = (1,000 pi / 360) = 8.727 cm (rounded)
What are different kinds of angle differentiate each angle?
Acute angle in the range (0, pi/2) radians = (0, 90) degrees.Right angle = pi/2 radians = 90 degrees.Obtuse angle in the range (pi/2, pi) radians = (90, 180) degrees.Straight angle = pi radians = 180 degrees.Reflex angle in the range (pi, 2*pi) radians = (180, 360) degrees.Full turn = 2*pi radians = 360 degrees.
What 2 times pi?
6.28It is also the angle in radians equivalent to an angle of 360 degrees.
What is the distance of one degree?
"one degree"= (2*Pi*r)/360 Your welcome
