The angle between two radii of a circle with radius 1.41m is 0.640rad . What length of arc is intercepted on the circumference of the circle by the two radii?
-
arc length = rθ
Think of it this way, if the angle was 2π radians (or 360°, an entire circle), the arc length would be 2πr - the circumference of a circle!
arc length = (1.41)(0.64) = .902m
