The radius of a circular disk is given as24cm 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.) cm²

(b) What is the relative error? (Round your answer to four decimal places.)

What is the percentage error? (Round your answer to two decimal places.) %

Suppose that we don't have a formula forg(x) but we know thatg(1) =4

andg'(x) =sqrt(x²+15)for allx.

(a) Use a linear approximation to estimateg(0.99) andg(1.01).

g(0.99)
