The volume of a sphere is decreasing at a constant rate of 9988 cubic centimeters per minute. At the instant when the volume of
Inessa05 [86]

Using implicit differentiation, it is found that the rate of change of the surface area of the sphere -2201.293 square centimeters per second.

<h3>What is the volume of a sphere?</h3>
  • The volume of a sphere, of radius r, is given by:

V = \frac{4\pi r^3}{3}

<h3>What is the surface area of a sphere?</h3>
  • The surface area of a sphere, of radius r, is given by:

S = 4\pi r^2

<h3>What is the rate of change?</h3>

Applying <em>implicit differentiation</em>, the rate of change of both the volume and the surface area can be found, as follows:

\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}

\frac{dS}{dt} = 8\pi r\frac{dr}{dt}

Volume of 3131 cubic centimeters, hence:

V = \frac{4\pi r^3}{3}

\frac{4\pi r^3}{3} = 3131

4\pi r^3 = 3(3131)

r = \sqrt[3]{\frac{3(3131)}{4\pi}}

r = 9.0754

The volume of a sphere is decreasing at a constant rate of 9988 cubic centimeters per minute, hence:

\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}

-9988 = 4\pi (9.0754)^2\frac{dr}{dt}

\frac{dr}{dt} = -\frac{9988}{4\pi (9.0754)^2}

\frac{dr}{dt} = -9.651

Then, the <u>rate of change of the surface area</u> of the sphere is given by:

\frac{dS}{dt} = 8\pi (9.0754)(-9.651) = -2201.293

The rate of change of the surface area of the sphere -2201.293 square centimeters per second.
