Mathematics for IGCSE & O level - Equations (Section 8 - No. 42)
If we want to make 'h' the subject of the formula V = (1/3)πr²h, what operation should be performed first?
Multiply both sides by 3
Divide both sides by π
Divide both sides by πr²
Subtract (1/3) from both sides
Explication
To isolate h, first undo the fraction, multiply both sides by 3: 3V = πr²h
