Question

How do I solve literal equations for the indicated variable

specifically Solve A=2pir^2+2pirh for the variable pi

Answer 1

A = 2pir² + 2pirh Factor out pi
A = (2r² + 2rh) pi Divide both sides by (2r² + 2rh)

`(A)/(2 r^(2) + 2rh )` = pi Flip the sides to make it easier to read
pi =
`(A)/(2 r^(2) + 2rh )`
