The formula for volume of a sphere is

To get radius from diameter, we must divide it by 2. 10/2=5, meaning the radius is 5 in.
Now, we just need to plug the values into the equation.
Answer:
Figure A sides are 1/4 the size of Figure B
The top of Figure A = 4, the top of Figure B = 1.
Divide 1 by 4 to get the scale factor, which is 1/4 as a fraction or 0.25 as a decimal.
