To determine the scale factor from the first sphere to the second.
Answer to Problem 23PPS
Explanation of Solution
Given:
Two spheres are similar.
The radius of the first sphere is 10 feet.
The volume of the other sphere is 0.9 cubic meters.
2.54 cm = 1
Formula used:
Volume of sphere
Calculation:
At first changing the radius from feet to meter,
Now, volume of the first sphere
The ratio of volume of sphere one and two gives the scale factor.
Multiplying 10 in both denominator and numerator,
So, the scale factor is
Conclusion:
Therefore, the scale factor from the first sphere to the second is
