Question

The error in the measurement of radius of a sphere
is 2% .What would be error in.
a volume of sphere
b. Surface area of Sphere
c. Total surface area of Hemisphere.​

Answer 1

Answer:

a. Volume of sphere = $\frac{4}{3}$π$r^{3}$

   Error = 3*2 = 6%

b. Surface area of sphere = 4π$r^{2}$

   Error = 2*2 = 4%

c. TSA of Hemisphere = 3π$r^{2}$

    Error = 2*2 = 4%
