126 + 44 = 170 ( total for under 25s)

186 - 56 = 130 (online for 25s - 50s)

154 - 58 = 96 ( in stores for aboves 50s)

314 for ONLINE TOTAL

196 for IN STORES TOTAL

510 for TOTAL TOTAL

A = 170

B = 56

C = 96

D = 96 - 58 = 38

The length of the arc intercepted by a central angle of 3/9 pie is 3.6 feet long. How long is the radius of the circle?
gtnhenbr [62]

Answer:

B) 3.44 feet

<em>The Radius of the circle 'r' = 3.439 ≅3.44 feet</em>

Step-by-step explanation

<u><em>Step(i)</em></u>:-

<em>Given data the length of arc = 3.6 feet long</em>

       l = 3.6 feet

Given central angle 'θ' =  \frac{3}{9} \pi

<u><em>Step(ii)</em></u>:-

The arc length 'l' of a circle of radius 'r' with central angle 'θ' radians is given by

Arc length l = r θ

<em>                  </em>3.6 = r (\frac{3}{9} \pi)

          put   π = 3.14

now simplification, we get

            r = \frac{3.6 X9}{3\pi }

           r = \frac{3.6 X9}{3X3.14 } = \frac{32.4}{9.42} = 3.439

<u><em>Conclusion</em></u>:-

<em>The Radius of the circle 'r' = 3.439 ≅3.44 feet</em>

12.464 is the 32% discount

38.95 - 12.464 = 26.486
