ANEK [815]

Answer:

h= 24

Step-by-step explanation:

$v = \pi {r}^{2} \frac{h}{3}$

$r = \frac{d}{2}$

$r = \frac{14}{2}$

r= 7

1230.88=3.14×7^2×h/3

1230.88= 153.86h/3

h=1230.88/153.86

h= 24

F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8

Elenna [48]

Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((|8 + 3| -1) - (|-6 + 3| -1))/(8 + 6) = ((|11| -1) - (|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7
