Answer:
b) 78.5
Step-by-step explanation:
The radius of the pizza is
10/2 = 5 inches
The area of a cirlcle is
A = πr^2
A = π(5)^2
A = 78.5
The resistance of a material is given by the formula R = ρ*
. Where l is the length and S is the area of the surface calculated with the radius, and ρ is the coefficient that indicates the resistance of a material.
If you keep the lenght and radius, and change the material, ρ will still change and the final resistance (R) will change.
