Answer:

The circumference of the inscribed circle is 37.68\ ft

Step-by-step explanation:

we know that

The circumference of a circle is equal to

C=\pi D

In this problem the diameter is equal to the length side of the square

so

D=12\ ft

substitute

C=(3.14)(12)=37.68\ ft

The diameter is 12 because the square's side is 12. The circumference is diameter * pi. 12 * 3.14 = 37.68. Hope that helped <span />

Convert the angle in degrees to radians. Express your answer as a multiple of π.
Elena L [17]
Converting 25 degrees to radians:

180° = π radians.

1° =  π/180  radians.

25° =  (π/180  radians) * 25

       =    (25/180) * π  radians.

Leaving the answer in terms of π,  25/180 = 5/36

=    (25/180) * π  radians = (5/36)π  radians  or ≈ 0.1389π radians.


Therefore 25° = (5/36)π  radians  or ≈ 0.1389π radians

I hope this explains it.

I think why you did not get it was because you did not leave your answer in terms of π or as a multiple of π, so as a multiple of π our answer is:

= (5/36)π  radians  or ≈ 0.1389π radians
