S=r*theta where s is arc length and the r is radius and theta is in RADIANS ONLY!! If you use degrees this formula does not work.

So we have a arc length of 38.485ft and a radius of 7. So rearranging the formula for theta, we get;

theta=(38.485)/(7)= 5.498radians then to convert to degrees if needed just take;

5.498rad*(180/pi)= 315deg

hank orders popcorn while watching a movie. the popcorn was served in a trapezoidal bucket. the height of the bucket is 10x-9 cm
Gnoma [55]

Area of the trapezoidal bucket, A is 130x² - 77x - 36 cm²

Step-by-step explanation:

  • Step 1: Area of a trapezoid = 1/2 (Sum of parallel sides) × Height

Sum of parallel sides = (10x - 2) + (16x + 10)

                                   = 26x + 8 = 2(13x + 4)

Height = 10x - 9

⇒ Area of the bucket = 1/2 × 2(13x + 4) (10x - 9)

                                    = (13x + 4)(10x - 9) cm²

                                    = 130x² - 117x + 40x - 36

                                A = 130x² - 77x - 36
