Question 162091: This is from a worksheet and I have two questions. Please Help
1. To the nearest tenth, what is the volume of a sphere whose radius is 1 yard? (V=4/3 pi r^3)
2. Solids A and B are similar. The height of solid A is 6 meters and the height of solid B is 15 meters. If the volume of solid B is 250 cubic meters, what is the volume of solid A?
I must show my work for both problems and am totally lost. Please help.

You can put this solution on YOUR website! 1. To the nearest tenth, what is the volume of a sphere whose radius is 1 yard? (V=4/3 pi r^3)

Just substitute 1 for r:
V =
Using a calc:
V =
V = 4.1888; rounded to 4.2 cu.yds

2. Solids A and B are similar. The height of solid A is 6 meters and the height of solid B is 15 meters. If the volume of solid B is 250 cubic meters, what is the volume of solid A?

Perhaps we can easily find a relationship here;
Assume we have 2 cubes,
6^3 = 216
15^3 = 3375
:
Using this relationship in a ratio: =
Cross multiply
3375A = 216 * 250
3375A = 54000
A =
A = 16 cu meters
