Suppose that 0 = 150 degrees

a. Find the length of the circular arc corresponding to 0(theda) on a circle of radius 5.

(For this question I got, 13.09, so could someone check to see if it's correct?)

b. Find the area of the slice corresponding to 0(theda) on a circle of radius 5

c. Find sin 0 and cos 0 (again 0 = theda)

d. Find the angle that the radial line segment of the unit circle ending at (sin 0, cos 0) makes with the positive horizontal axis.

I would GREATLY appreciate it if you guys could also provide the answers just for proofing and rechecking.
