can you answer this question asap and show all of the work?

Suppose a 3 in schedule 80 steel pipe is covered with 1 in of an insulation having k=60mW/mC and the outside of the insulation is exposed to an environment having h=10W/m2C and Tf=20C. The temperature of the inside of the pipe is 250C. For unit length of the pipe calculate (a) the overall thermal resistance and (b) the heat loss (in Watts)
