B. 13.9 yards
To find the radius of the circle, we can use the formula:
Arc length = radius x central angle
3.8 = r x 1.9
r = 3.8 / 1.9
r = 2
Therefore, the radius of the circle is 2 yards.
An arc with a length of 3.8 yards has a central angle that measures 1.9 radians. What is the radius of the circle?
A. 7.2 yards
B. 13.9 yards
