Question

A=4ℼR2 solve for R
SHOW ALL STEPSSSSSSSSSSSSS

Answer 1

Given problem;

A = 4 π R²

To solve for R, we have to make it the subject of the expression.

Since

A = 4 π R² , follow these steps to find R;

Multiply both sides by
`(1)/(4\pi )`

A x
`(1)/(4\pi )` =
`(1)/(4\pi )` x 4 π R²

`(A)/(4\pi )` = R²

Then find the square root of both sides

√R² =
`\sqrt{(A)/(4\pi ) }`

R =
`\sqrt{(A)/(4\pi ) }`

The solution is
`\sqrt{(A)/(4\pi ) }`
