Question

Heyyy.... can someone pls help asap. Rearrange the formula to write r in terms of P and pi.


`p = 2r + \pi \: r`
​

Answer 1

r =
`(p)/(2+\pi )`

Explanation:

p = 2r + πr ← factor out r from each term

p = r(2 + π) ← divide both sides by (2 + π )

`(p)/(2+\pi )` = r

Answer 2

Explanation:

p = 2r + pi×r

p = r(2 + pi)

r = p/(2 + pi)
