Answer:
Step-by-step explanation:
To solve an equation for one of its variables do that:
- Underline the variable
- Separate it one side and the other terms on the other side
- Make its coefficient equal to 1
Let us use these steps to solve our question
∵ V = πr²h
→ Underline r²
∴ V = π<u>r²</u>h
→ Take π and h to the other side by dividing both sides by πh
∵
∴
→ The coefficient of r² is 1, so switch the two sides
∴
