Make the variables in brackets the subject

(π=pie)

Make the variables in the brackets the subject
A) A = πR².........(R)
B) (A + B)² = C.......(B)

Transpose the following equations

A) V² = U² +2AS.........(A)
B) A = 2π² + 2πrh...........(H)

Would be good if you could give it step by step and not just the answer
thanks :D

A1)
A = πR^2
R^2 = A/π
R = SQRT(A/π)

B1)
(A+B)^2 = C
A^2 + 2AB + B^2 = C^2
B^2 + 2AB + (A^2 - C^2) = 0

using the quadratic formula with a = 1, b = 2A, and c = (A^2 - C^2) we get:

B = -A +/- C

A2)
V^2 = U^2 + 2AS
2AS = V^2 - U^2
A = (V^2 - U^2) / 2S

B2)
A = 2π^2 + 2πrH
2πrH = A - 2π^2
H = (A - 2π^2) / 2πr

Best of luck!
