Find the first partial derivative with respect to r
Find the first partial derivative with respect to h
∂r∂v=32πrh
Evaluate
v=31πr2h
Multiply the numbers
v=3πr2h
Find the first partial derivative by treating the variable h as a constant and differentiating with respect to r
∂r∂v=∂r∂(3πr2h)
Use differentiation rule ∂x∂(cf(x))=c×∂x∂(f(x))
∂r∂v=3πh×∂r∂(r2)
Use ∂x∂xn=nxn−1 to find derivative
∂r∂v=3πh×2r
Solution
∂r∂v=32πrh
Show Solution

Solve the equation
Solve for h
Solve for r
Solve for v
h=πr23v
Evaluate
v=31πr2h
Multiply the numbers
v=3πr2h
Swap the sides of the equation
3πr2h=v
Divide both sides
3πr23πr2h=3πr2v
Divide the numbers
h=3πr2v
