A circle with an area of 49π square meters has a central angle that traces out an arc of 21 meters. What is the the radian measure of the central?

8 apples are left.

step-by-step explanation:

10-2=8

10 apples

take 2

now u have 8

goog may have it for you

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
