The radius of a circular disk is given as cm with a maximum error in measurement of cm. Use differentials to estimate the maximum error in the calculated area of the disk. What is the relative error? What is the percentage error?

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

what i would say the best answer is a. 40.5

70

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
