Find T in terms of K, Q and S if S = 2r((piQT + K)

A.
(frac{S^2}{2 pi r^2Q} – frac{k}{Q}) 
B.
(frac{S^2}{2 pi r^2Q}) – k 
C.
(frac{S^2}{4 pi r^2Q} – frac{k}{Q}) 
D.
(frac{s^2}{4 pi r^2Q})
Correct Answer: Option B
Explanation
(frac{s^2}{4r^2}) = QT(pi) + KT
(frac{s^2}{4r^2}) – k(pi) = QT(pi)
T = (frac{s^2}{4Qpi r^2}) – k
