Answer:
ow do you find arc length without the radius?
To calculate arc length without radius, you need the central angle and the sector area:
Multiply the area by 2 and divide the result by the central angle in radians.
Find the square root of this division.
Multiply this root by the central angle again to get the arc length.
The units will be the square root of the sector area angle.

Or the central angle and the chord length:
Divide the central angle in radians by 2 and perform the sin function on it.
Divide the chord length by double the result of step 1. This gives you the radius.
Multiply the radius by the central angle to get the arc length.

Answer:
   y = -7x
Step-by-step explanation:
The line goes through the origin, so the y-intercept is b=0.
The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...
   m = rise/run = -7/1 = -7
Then the slope-intercept form equation is ...
   y = mx + b
   y = -7x
 
        
             
        
        
        
Answer:
Rs 1000.97 
Step-by-step explanation:
x = original price 
new price =   x (1.0909)(1.0833)(1.077) = 1274 
                          x = Rs 1000.97
