Here's the question you clicked on:
v.s
A machinist is required to manufacture a circular metal disk with area 500 cm2. (a) What radius produces such a disk? (Round your answer to four decimal places.) cm (b) If the machinist is allowed an error tolerance of ±7 cm2 in the area of the disk, how close to the ideal radius in part (a) must the machinist control the radius? (Round your answers to four decimal places.) cm < r < cm
i need help with the second part
a) Because area=pi*r^2 Solve for r (r=12.6157) b) To solve the second part, do the same thing you did for part a using areas 507 and 493. Does that make sense?
(c) In terms of the ε, δ definition of lim x→a f(x) = L, what is x? area target radius radius target area tolerance in the area
I'm sorry, I can't! You just went beyond my ability level :) Good luck!
