Solve b=l/4 pi d^2

Evaluate

b = \frac{l}{4} π d^{2}

Multiply the terms

More Steps

b = \frac{π l d ^{2}}{4}

Find the first partial derivative by treating the variable d as a constant and differentiating with respect to l

\frac{\partial b}{\partial l} = \frac{\partial}{\partial l} (\frac{π l d ^{2}}{4})

Use differentiation rules

\frac{\partial b}{\partial l} = \frac{1}{4} \times \frac{\partial}{\partial l} (π l d^{2})

Calculate the derivative
