certain pond absorbs I $=715$ W$/$m$2$ for a time period of an hour from the sun. Assume that all of this energy is used to raise the temperature of the pond. The pond water fills a hemisphere of radius r $=2\mathrm{.}75$ m and has a density $=1000$ kg$/$m$3.$ The specific heat of the pond water is c $=4186$ J$/($kg$$K$).$

What is the change in temperature $$T in kelvins of the pond due to this energy transfer?
