Answer 1

P = 2b + 2h
P - 2h = 2b
2b = P - 2h
b = (P - 2h)/2
-------------------------------------------------
A = bh
A/h = b
b = A/h
-------------------------------------------------
A = bh
A/b = h
h = A/b
-------------------------------------------------
V = bha
V/bh = a
a = V/bh
------------------------------------------------
P = 2πr
P/2π = r
r = P/2π
-------------------------------------------------
A = πr²
A/π = r²
r² = A/π
r = √A/π
------------------------------------------------
A = 4πr²
A/4π = r²
r² = A/4π
r = √A/4π
------------------------------------------------
v = 4/3πr³
v/4/3π = r³
r³ = v/4/3π
r = ∛v/4/3π
----------------------------------------------
A = πr²
A/π = r²
r² = A/π
r = √A/π
--------------------------------------------------
v = πr²h
v/πr² = h
h = v/πr²
----------------------------------------------
v = 1/3πr²h
v/1/3πr² = h
h = v/1/3πr²
----------------------------------------------
A = πr (r² + h²) + πr²
A - πr² = πr (r² + h²)
(A - πr²)/πr = r² + h²
A - r = r² + h²
A - r - r² = h²
h² = A - r - r²
h = √(A - r - r²)
