Question

The percentage error in the volume of sphere is 6%. Then find the error in surface area of the sphere.
In this why we took ΔV/V=(4/3πr³)/(4/3π3r²Δr)

Answer 1

Dear friend we take ∆V/V because to find the percentage error we have to divide the error that comes by original value and multiply by 100 to get percentage error but in question already given percentage error but to find the radius we have to do ∆ V / V
