Answer:
452.16 is the answer!
Explanation
the volume of a cone is radius times radius times height times pi(3.14) to equal the volume.
so let do it backward to find the height oh Figure A. 25.12 divide 3.14 is 8, 8 divide 2 times 2 is 2, so 2 is the height of Figure A.
since Figure B is 3 times Figure A, the height of Figure B will NOT be 3 times but 2 times Figure A which is 4. Now we can calculate the volume of Figure B, 6 times 6 times 4 times pi(3.14) = 36 times 4 times 3.14 = to 144 times 3.14 = 452.16 and that the volume and answer of Figure B.
