Give me 10 equations in which I must change the subject of the formula

1) Change the subject in the equation A = l * w to solve for the length, l.

Solution: l = A / w

2) Rearrange the equation V = l * w * h to solve for the width, w.
Solution: w = V / (l * h)

3) Change the subject in the equation E = mc^2 to solve for the speed of light, c.
Solution: c = √(E / m)

4) Rearrange the equation F = m * a to solve for the mass, m.
Solution: m = F / a

5) Change the subject in the equation r = π * d to solve for the diameter, d.
Solution: d = r / π

6) Rearrange the equation P = 2(l + w) to solve for the width, w.
Solution: w = (P - 2l) / 2

7) Change the subject in the equation I = V / R to solve for the resistance, R.
Solution: R = V / I

8) Rearrange the equation C = 2πr to solve for the radius, r.
Solution: r = C / (2π)

9) Change the subject in the equation T = (C - F) * 9/5 + 32 to solve for the Celsius temperature, C.
Solution: C = (T - 32) * 5/9

10) Rearrange the equation A = πr^2 to solve for the radius, r.
Solution: r = √(A / π)
