18 is the answer im pretty sure if its wrong im sorry
The explanation of using Literal equations to solve for a given variable is as explained below.
How to solve Literal Equations?
Literal equations are equations containing two or more variables; at least one independent variable and one dependent variable
To solve a literal equation means to rewrite the equation so a different variable stands alone on one side of the equals sign. We have to be told for which variable we want to solve.
Linear equations in one variable may take the form ax + b = 0 and are solved using basic algebraic operations.
We begin by classifying linear equations in one variable as one of three types: identity, conditional, or inconsistent. An identity equation is true for all values of the variable.

Answer:
A
Step-by-step explanation:
these two triangles are similar
therefore corresping sides are proportionate
12/8=9/x
12x=72
x=72/12=6
The way you put it is confusing. I'll answer but the way you put it was confusing to me.
Answer - to solve for the equivalent equation of r you would need to use the formula r=c/pi2.
