c. use h button on your calculator, and express your answer to the nearest ndredth.

Circumference of the given circle:

C=88 cm

a) Exact answer in terms of

b) By using

C)

Step-by-step explanation:

Given that the radius of a circle is 14cm

That is r=14cm

To find the circumference of the given circle:

(where )

Therefore C=88cm

a, Exact answer in terms of

b, By using

C,

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

the answer is 0.3175 hope that you ^w^
