"Suppose that I don't have a formula for #g(x)# but I know that #g(1)
= 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

Circumference = pi(diameter)
Pi times diameter
Explanation:
Sometimes to find the diameter, you must multiply the radius by two to get the diameter; the radius is half the diameter and is from the center of the circle to the edge/rim whatever you want to call it. Pi also equals 3.14159265358979323... etc. It goes on forever. But most people just use 3.14.
