Circumference = 2 * PI * radius
Circumference = 2 * 3.14159265 * 63
Circumference = 395.841
The formula for area of a trapezoid is
![\frac{(b1 + b2) \times h}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%28b1%20%2B%20b2%29%20%5Ctimes%20h%7D%7B2%7D%20)
so you add up the bottom base (17) and the top base (3) to get 20.
you then take the sum of the bases (20) times the height (8) to get 160.
lastly, you take 160 ÷ 2 to get your final answer, which is 80 (:

Answer:
Step-by-step explanation:
Average rate of change is the same thing as the slope. Because this is parabolic, we cannot find the exact rate of change as we could if this were a linear function. But we can use the same idea. When t = 3, h(t) = 33, so the coordinate point is (3, 33). When t = 6, h(t) = 0, so the coordinate is (6, 0). Plug those values into the slope formula:
and
which is -11
