## Homework Statement

The bottom of a circular, aluminum pot has a radius of 8cm and a thickness of 1cm. The temperature of the stove top is 120 degrees celsius and the temperature of the pot initially is 20 degrees celsius. What is the rate at which energy is transferred through the bottom of the pot?

a. 300W

b. 2589W

c. 2.67X10^5W

d. 4.79X10^4W

e. 7.89W

## Homework Equations

P=KA(TH-TC)/L

## The Attempt at a Solution

[/B]

Thermal Conductivity(K) of Aluminum: 220 k (J/s⋅m⋅ºC)

A(Cross sectional area the energy goes through): .08m??

(Th-Tc): (120-20degreeC)

L(Distance energy travels): .01m?

Im not sure if this is the right equation to use, or if A or L is correct. I am not getting the answer this way.
