Question 1127809
A circle with a radius of 3.8 cm is centered at the vertex of an angle. Suppose the angle has a measure of 160 degrees.

a. What is the radian measure of this angle?
160º = 160*pi/180 = 8pi/9 radians.
=======================

b. What is the length (in cm) of the arc subtended by the angle's rays along the circle?
L = r*T (T in radians)
=======================
c. Suppose T represents the varying degree measure of the angle. Write an expression that represents the length (in cm) of the arc subtended by the angle's rays along the circle.
L = T*r*pi/180 --- T in degrees
