WebHow many radians are there in a full circle - How many radians in a full circle? ; Answer: 6.283 ; Circumference ; Circumference ; Circumference ; 2. A. ... There are 2 radians in a whole circle, which means that half a circle (180) is equal to radians. This comparison means that: 360=2 radians 180= WebThe radius of the circle = 6 inches. The angle subtended by the arc = 1.5 radians. We know that the arc length is the product of the radius and the angle subtended by the arc at the center of the circle. So arc length = (6) (1.5) = 9 inches. Answer: Arc length = 9 inches.
