375 . 600 = 225000
225000÷1000
x = 225
cos(2<em>θ</em>) + sin²(<em>θ</em>) = 0
Half-angle identity:
cos(2<em>θ</em>) + (1 - cos(2<em>θ</em>))/2 = 0
Simplify:
2 cos(2<em>θ</em>) + 1 - cos(2<em>θ</em>) = 0
cos(2<em>θ</em>) = -1
Solve for <em>θ</em> :
2<em>θ</em> = arccos(-1) + 2<em>nπ</em>
2<em>θ</em> = <em>π</em> + 2<em>nπ</em>
<em>θ</em> = <em>π</em>/2 + <em>nπ</em>
where <em>n</em> is any integer.

Answer:
A. 24 hm
Step-by-step explanation:
The formula for the circumference of a circle is ...
C = 2πr
Fill in the given values and solve.
150.7968 hm = 2×3.1416×r
(150.7968 hm)/6.2832 = r = 24 hm . . . . . divide by 2π
The radius of the circle is 24 hm.
