Make h subject of formula.calculate s= 2πr (r+h)

Answer 1

To make h the subject of the formula, we need to isolate h on one side of the equation.

Given formula: s = 2πr(r + h)

Start by expanding the brackets:

s = 2πr^2 + 2πrh

Rearrange the equation to isolate h:

2πrh = s - 2πr^2

Divide both sides of the equation by 2πr:

h = (s - 2πr^2) / (2πr)

Therefore, h = (s - 2πr^2) / (2πr) is the formula where h is the subject.
