Here are you're answers:
1. A literal equation is a equation where "each of the variables also represent known values." A example of a literal equation is [tex]2300 = 3500 + r[/tex].
2. The answer is "yes." Literal equations can have pi symbols there is a formula that can help solve literal equations. That formula is [tex]V = \frac{\pi}{3} r^2h[/tex].
Hope this helps!
