Answer:
its B) 22
Step-by-step explanation:
:) ........bbbbbb
The ratio figure b to figure a 1/3. Just times 6 by 3 and the you'll find that the volume of figure a is 18.
To determine the time it takes for the maximum height to be achieved, derive the equation and equate to zero.
h = -16t² + 112t + 30
dh / dt = 0 = 2(-16)t + 112
The value of t is 3.5 s. Substitute this value of time to the equation for h,
h = -16 x (3.5 s)² + 112 x 3.5 s + 30 = 226 ft
Thus, the answer is letter D.
