Given : The radius of a sphere is (20.0 +0.2) cm

To find : The percentage error in its surface area

Solution:

Surface area of sphere A = 4πR²

ΔA/A   =  2ΔR/R

=> 100 * ΔA/A  = 100 * 2ΔR/R

=> Percentage error in Surface Area =  2 ( Percentage error in Radius)

=> Percentage error in Surface Area =  100 * 2 * 0.2/20

=>  Percentage error in Surface Area = 2  

 The percentage error in its surface area is 2 %
