Solve this problem using English units; do not convert

this problem to SI$.$ You have a $5\mathrm{.}3$ inch diameter sphere

heated to $335\mathrm{.}0F,$ which is inside of a large room with a

surrounding temperature of Tsurr $=71\mathrm{.}0F.$ Treating the

sphere as a blackbody, calculate the net heat transfer

rate due to radiation between the sphere and its

surrounds, in units of BTU$/$hr$.$ The Stephan$-$Boltzmann

Constant in English units is: $={1\mathrm{.}714}^{*{10}^{-9}}BT\frac{U}{hr-f{t}^2}$
