Answer:

Step-by-step explanation:
Radius = r = 9 cm
Angle = θ = 200° = 3.5 radians
Now,

Area = 1/2 (9)²(3.5)
Area = 1/2 (81)(3.5)
Area = 282.7 / 2
Area of sector = 141.4 cm²
Answer:

Step-by-step explanation:
The equation given is 
and also we have that
, thus:

------------
I think the question is missing which variable is defined as
, so I will solve for
since is the only other variable in the equation.
substituting
into
:

and we solve for m:

m is equal to 18.
