Question

Q2/60 The percentage error in the measurement
of radius of sphere is 2%. Then the maximum
percentage error in the measurement of surface
area of sphere will be?

Answer 1

Answer:

the percentage error in the measurement of radius is 2 percent the maximum percentage error is measurement of surface is 4

Answer 2

Answer:

8%

Explanation:

Surface area of sphere is calculated as: A=4πr^2

Lets say radius is less by 2%. If we have 2% error in value of r, it will be 98% of previous value. The new value for A=4π(0.98r)^2=4πr^2*0.92

So percentage error= 8%
