Knowing that your area is: A= \pi  r^{2}=36  in^{2} you can find the radius as:
r= \sqrt{ \frac{36}{ \pi } } =3.4 in;
With this you can evaluate the circumference as:
C=2 \pi r=2*3.14*3.4=21.3 in

diamong [38]

Answer:

See below in bold.

Step-by-step explanation:

(1) cosec ( x + 10) = 3

Now cosec x = 1/sin x so

1 / sin (x + 10) = 3

3 sin (x + 10) = 1

sin (x + 10) = 1/3

x + 10 = 19.47 , 160.53 degrees

x = 9.47, 150.53 degrees.

(ii) cot (x - 30) =0.45

cot (x - 30)= 1 /tan (x- 30) so we have

tan (x - 30) = 1 / 0.45 = 2.2222

x - 30 = 65.77 degrees

x = 95.77 degrees.
