Solve for π: V= 2πr^2 + 2πrh
crimeas [40]

Answer:

π = V/(2r²+2rh)

Step-by-step explanation:

"Solving" for something means to isolate it on one side of an equation. Because both terms on the right side of the equation have π in common, we can factor it out. Then from there, you just divide the rest of it on both sides to isolate π. It should look like this:

V=2πr^2 + 2πrh

V=π(2r² + 2rh)

V/(2r² + 2rh)=π
