The maximum height of the object is 82.7034 from the ground
<h3>What is Velocity ?</h3>
Velocity is the measure of movement of an object with respect to time.
It is measured in m/sec
h = -4.9t²+21.6t +58.9
dh/dt = -9.8t +21.6
At maximum height , velocity = 0
therefore
-9.8t +21.6 = 0
9.8t = 21.6
t = 2.204 sec
h = -4.9 (2.204)²+ 21.6 * 2.204 +58.9
h = -23.803 +47.606 +58.9
h = 82.7034 from the ground
h = 23.80 from the point it is launched.
The maximum height of the object is 82.7034 from the ground

Answer:
A) 216 in²
Step-by-step explanation:
2(1/2)(6)(4)=24
2x5x12=120
6x12=72
24+120+72=216
Volume=(pi)(radius^2)(height)
245(pi)=(pi)(r^2)(5)
245=(r^2)(5)
49=r^2
radius=7
diameter=14
