Given:
Central angle = 
Arc length = 1.5 in
To find:
The radius of the circle.
Solution:
We know that the formula for arc length is
Where r is radius and 
is the central angle in radian.
Substitute the given values in the above formula.
On further simplifiation, we get
Therefore, the radius of the circle is 1.91 in.
Answer:
(−1) (+4)
Step-by-step explanation:
Answer:
Cos theta = sin(90-theta)
so cos 71 = sin(90-71)
cos 71 = sin( 19)
Therefore the answer = sin(19) = 0.14987720966
