>A. Figure AB. Figure Bc. they are equalD. need more information

Answer:
B. Figure B
Explanation:
Figure A
Figure A is a square pyramid. The volume of the square pyramid is calculated below:
[tex]\begin{gathered} V=\frac{1}{3}\times Base\text{ Area}\times Height \\ =\frac{1}{3}\times5^2\times6 \\ =50\text{ cubic units} \end{gathered}[/tex]Figure B
Figure B is a cylinder. The volume of the cylinder is calculated below:
[tex]\begin{gathered} V=\pi r^2h \\ =3.14\times1^2\times50 \\ =157\text{ cubic units} \end{gathered}[/tex]Thus, we can see that Figure B has a greater volume.
The correct option is B.
