B.
The figure has a cone and a half sphere.

C.
The volume of the composite figure is approximately 904.3 cubic feet.

D.
The volume of the composite figure is approximately 523.3 cubic feet.

Answer 1

b

Step-by-step explanationtit obviously looks like a semi-circle and a cone. >:|

Answer 2

B. and D.

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.
