Good Morning please sir I need help with this question: A=2πr(r+h) make r the subject of formular. Hence find r when A=770, π=22/7 and h=7

Thanks for this. But I like to know why the square still remains in question 2a

[@OninabResources]

The square must still remain because it's difference of two squares and not a perfect square. If we have it as (z - y)² inside the square root, then the square will remove the square root. Thank you for watching. We also appreciate your feedback. Help us share the link to others.🙏
