The original volume is given by:
V1 = (4/3) * (pi) * (r1 ^ 3)
V1 = (4/3) * (3.14) * (3 ^ 3)
V1 = 113.04 cm ^ 3
The current volume is given by:
V2 = (4/3) * (pi) * ((r1 + 0.25 * t) ^ 3)
V2 = (4/3) * (3.14) * ((3 + 0.25 * 4) ^ 3)
V2 = 267.9466667 cm ^ 3
The relation of volumes is:
V2 / V1 = 64/27
Answer:
The ratio of the current volume of the snowball to the original volume of the snowball is:
V2 / V1 = 64/27

The correct answer is:

15 bicycles and 6 skateboards.

Explanation:

Let x represent the number of bicycles and y represent the number of skateboards. The first equation in our system is then

x+y = 21, since there are 21 total items in the shop.

Each bicycle has 2 tires and each skateboard has 4; this gives us the equation

2x+4y=54 (because they are ordering 54 tires).

This makes our system

$\left \{ {{x+y=21} \atop {2x+4y=54}} \right.$

We will use elimination to solve this; we first need one of the variables to have the same coefficient in both equations. We will make x the same, and we will do this by multiplying the first equation by 2:

$\left \{ {{2(x+y=21)} \atop {2x+4y=54}} \right. \\
\\\left \{ {{2x+2y=42} \atop {2x+4y=54}} \right.$

Now we will subtract the second equation from the first one:

$\left \{ {{2x+2y=42} \atop {-(2x+4y=54)}} \right. \\
\\-2y=-12$

Divide both sides by -2:

-2y/-2 = -12/-2

y = 6

There were 6 skateboards. Substituting this into the first equation,

x+6 = 21

Subtract 6 from each side:

x+6-6 = 21-6

x = 15

There were 15 bicycles.
