Read each question carefully and follow the instructions to manipulate the given formulas. Show all your work.

1. The formula for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width. Rearrange the formula to solve for the width (w).

2. The formula for the perimeter of a square is P = 4s, where P is the perimeter and s is the side length. Rearrange the formula to solve for the side length (s).

3. To solve the equation d = rt for t, you would both sides by r.

4. In the formula I = PRT, if you want to find R, you need to I by PT.

5. Which of the following correctly rearranges the formula C = 2πr to solve for r?

r = C - 2π

r = C / 2π

r = 2π / C

r = C + 2π

6. To solve the formula V = lwh for h, you would divide both sides by lw.

True

False

7. The formula for the volume of a cylinder is V = πr²h. Rearrange the formula to solve for the height (h).

8. The formula for converting Celsius to Fahrenheit is F = (9/5)C + 32. Rearrange the formula to solve for Celsius (C).
