Find

(a) the value of q in radians

(b) the area of the shaded region in cm²

(a) 1.18

(b) 99.71

Step-by-step explanation:

to know the value of q in degrees we can use cosine of q

now to radians

the formula is

with x the degrees

so the measure of angle q is 1.18 radians

so now for part b

with being the central angle in radians

for degrees is the following

so we have

cm^2

b.-4 units

all you   do is count how many times you move

the radius is 2 times the diameter.
