Answer:
Answer: 284.7
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(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
b=60
6+4/5b=9/10b
-4/5b -4/5b
6=1/10b
divide both sides by 1/10
y = 5
cross-multiply:
6y = 30
