Question

This is for literal equations
A=4 πr2 (r2)

i think you solve for r2

Answer 1

`r^2=(A)/(4\pi)`

Explanation:

The given equation is A=4 πr².

We need to solve the above equation for r².

We have,

A=4πr²

Dividing both sides by 4π, we get :

`(A)/(4\pi)=(4\pi r^2)/(4\pi)\\\\r^2=(A)/(4\pi)`

Hence, the value of r² is equal to
`(A)/(4\pi)`.
