Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*![\pi r^{3}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B3%7D)
=(1/2)*(4/3)*3.14*
(4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)
h
=(1/3)*3.14*
*9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
