Answer : 8 ft
Explanation :
You can find the volume of a regular square pyramid using the formula volume = base area × height / 3. Hope it helps.
There is no X But Y is (0,5)
H'=-32t+96
0=-32t+96
-96=-32t
3=t
3 seconds
H=-16t^2+96t+3
H=48^2+288+3
H=48^2+291
Volume of cone=1/3 times height times pir^2
v=15
r=3
15=1/3 hpi3^2
15=1/3hpi9
15=9/3hpi
15=3hpi
divide 3
5=hpi
h=5/pi
pi=aprox 3.14
5/3.14=1.59
1.59 ft
