The radius r of a sphere changes at a rate of 8 cm/s. Then which of the following statements is true regarding the ratio of the rate of change in volume to the rate of change in Surface Area with respect to time? |
The ratio depends on r The ratio doesn't depend on \[ { r }^{ 2 } \] The ratio depends on \[ { r }^{ 3 } \] The ratio depends on \[ { r }^{ 4 } \] |
The ratio depends on r |
(dV/dt ) / (dS/dt) = r/2 |
