The radius r of a sphere changes at a rate of -2 cm/s. Then which of the following statements is true regarding the ratio of the rate of change in Surface Area to the rate of change in volume with respect to time? |
The ratio depends on \[ { r }^{ 2 } \] The ratio depends on \[\frac{1}{ { r }^{ 2 } }\] The ratio depends on r The ratio depends on /r |
The ratio depends on /r |
\[\frac{dS/dt}{dV/dt}=2/r\] |
