If s denotes the length of the arc of a circle of radius r subtended by a central angle \theta , find the missing quantity.

s = 7.02 meters, \theta = 2.6 radians, r = ?
a. 0.37 m
b. 3.6 m
c. 1.35 m
d. 2.7 m

The correct answer would be D. 2.7 m meters. 

To solve this,
v=s/r
since we have s = 7.02 meters, \theta = 2.6
Then 
7.02/2.6 = 2.7m

The correct answer is d. 2.7 m. This is the missing quantity which is the radian.

Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help. 

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
