the diameter of a circle is to be measured and its area compute. if the diameter can be measured with a maximum error of 0.0002 cm. and the allowable error in the area is 0.01 cm^2, find the diameter of the largest circle for which the specifications are met.

Hint:

Area of a circle = π * r²
dA = 2 * π * dr
