Since we are dealing with volume, a difference in radii produces a change in the volume CUBED.3^3 = 274^3 = 64
64 / 27 = <span> <span> <span> 2.3703703704 </span> </span> </span>
So, the larger sphere will have <span> <span> <span> 2.3703703704 </span>times more volume than the smaller sphere.

The larger of two numbers is five more than the smaller number. If the sum of the numbers is 59, find the numbers
Andrews [41]

Answer:

27 and 32.

Step-by-step explanation:

Let the two numbers be A and B.

The larger number (let's use B) is 5 more than the smaller one (A). In other words:

B=5+A

Their sum is 59. So:

A+B=59

This is a system of equations. Solve by substituting the first equation into the second. Thus:

A+(5+A)=59

Combine like terms:

2A+5=59

Subtract 5 from both sides:

2A=54

Divide both sides by 2:

A=27

So, the smaller number is 27.

This means that the bigger number is 27+5=32.

So, the two numbers are 27 and 32.

And we're done!
