A 2.5 cm length of tungsten filament in a

small lightbulb has a resistance of 0.041

.

Find its diameter. (The resistivity is

5.6 × 10−8

· m).

Answer in units of mm.

2. Relevant equations

R=P(L/2pi*rsquared)

3. The attempt at a solution

i keep getting 20856 m as my answer but it is wrng when i entr it i plugged in everything and made sure everything was to the right unit so dont know what is wrong
