A circle has a diameter of 10 meters. What is the length of the arc subtended by a central angle of 4 radians. A. 40 meters
B. 20 meters
C. 4 meters
D. 10 meters

Use continuity to evaluate the limit. lim x→16 20 + x 20 + x step 1 consider the intervals for which the numerator and the denominator are continuous. the numerator 20 + x is continuous on the interval the denominator 20 + x is continuous and nonzero on the interval
