Question

A=2pir^2+2pirh solve for pi

Answer 1

Well you would have to get Pi by itself so...
A = 2pir^2+2pirh / 2pir
A/2pir = pir(h) and then divide h
A/2pirh = pir and just multiply by 2pir
A/H = 3pir^2 and divide by 3r and square root it
√ A/3rH = pi
((I know there is a simpler way but it's hard to type it out T-T Sorry if this was confusing))

Answer 2

The value of the expression for π is
`\pi=(A)/(2 r^2+2rh)`

Explanation:

Consider the provided equation.

`A=2\pi r^2+2\pi rh`

We need to solve the equation for π.

Take π common.

`A=\pi (2 r^2+2rh)`

Divide both the sides by
`2 r^2+2rh`

`(A)/(2 r^2+2rh)=\pi`

`\pi=(A)/(2 r^2+2rh)`

Hence, the value of the expression for π is
`\pi=(A)/(2 r^2+2rh)`
