Answer
To equate the two volumes, we start by using the formula for the volume of a shape. We know that the volume of a shape can be expressed as:
V = rac{1}{3} imes ext{Base Area} imes ext{Height}
By applying this concept, we can set two volume expressions equal to each other.

Answer
The next step involves equating the surface areas. For example, if we have surfacing area expressions, say:
extSurfaceArea=r2imesextareafactor
we can manipulate this to derive relevant parameters.

Answer
Substituting ext√5 into the equations is necessary to find a specific relation. We might have expressions such as:
A=ext√(r2+5)
This substitution will help clarify the relationship among variables.

Answer
After we substitute the value for t, the next step is to isolate the term in r. This can be achieved by rearranging the equation as follows:
r = rac{t}{ ext{any constant}}
