Question

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate the maximum error in the calculated area of the disk. (Round your answer to two decimal places.)

Answer 1

30.17 cm

Explanation:

area of a circular disc=π*r^2

derivative of area=2*π*r

maximum error= derivative * error in radius

i.e . 2*π*r*0.2
