Step 1: Rewrite using exponentsMust rewrite using exponents!10A conical tank with height of 4 ft is being filled with water.

Write the equation for the volume of the conical tank.

Find the instantaneous rate of change equation of the volume with respect to the radius.

Find the instantaneous rate of change in Volume when the radius is 9 ft.

When the radius is 9 the volume increases 24cu.ft.per minuteSecond and Higher Order Derivatives
