therefore
velocity=184 divide by 92 = 2 m/s
Answer:
-7k+21
Step-by-step explanation:
Answer:
Step-by-step explanation:
volume of cylinder = πr²h
πr²h = 127.23 cubic inches
3.14 * 3 * 3 * h = 127.23
h = 127.23 / 3*3*3.14
=127.23 * 100 /3*3*3.14*100
=12723/ 3*3*314
= 4241 / 3*314
=4241/ 942
=4.502 inches
h = 4.5 inches
