Rearranging Formulas Challenge

Rearrange the formula P = 2L + 2W to make W the subject.

• W = 2L - P

• W = P / 2L

• W = P - 2L

• W = (P - 2L) / 2

Given the formula A = πr^2, rearrange it to make r the subject.

• r = A/π

• r = A^2/π

• r = √(A/π)

• r = π/A

If the formula F = ma, rearrange it to make a the subject.

• a = F - m

• a = F * m

• a = F/m

• a = F + m

Rearrange the formula V = πr^2h to make h the subject.

• h = V + πr^2

• h = V / (πr^2)

• h = V - πr^2

• h = V * πr^2

Given the formula T = 2π√(l/g), rearrange it to make l the subject.

• l = T² / 2πg

• l = T * 2π√g

• l = (T/2π)² * g

• l = T² * g / 2π

If the formula C = 5/9(F-32), rearrange it to make F the subject.

• F = 5/9C + 32

• F = 5/9C - 32

• F = 9C - 32

• F = 9/5C + 32

Rearrange the formula E = mc^2 to make m the subject.

• m = E/c^2

• m = c^2/E

• m = c^2/E

• m = E*c^2

Given the formula I = V/R, rearrange it to make R the subject.

• R = I/V

• R = V/I

• R = V+I

• R = I*V

If the formula P = 2(a+b)/2, rearrange it to make a the subject.

• a = P - b

• a = P / 2 - b

• a = 2P - b

• a = P + b

Rearrange the formula S = √(s^2 - 4t) to make t the subject.

• t = (s - S) / 4

• t = S^2 / (s^2 - 4)

• t = (s^2 - S^2) / 4

• t = √(s^2 - 4) / S
