Answer:
B. and D.
Step-by-step explanation:
B.:
The top shape is a hemisphere (half sphere) and the bottom shape is a cone.
D:
Hemisphere:
V=[(4/3)pi*r^3]/2
V=[(4/3)pi*5^3]/2
V=[(4/3)pi*125]/2
V=523.333/2
V=261.6667
Cone:
V=1/3*pi*r^2*h
V=1/3*pi*5^2*10
V=1/3*pi*25*10
V=261.6667
Added together is about 523.3 cubic feet.
