As you eat your way through a bag of chocolate chip cookies, you observe that each cookie is a circular disk with a diameter of = 8.92 1×10^−2 and a thickness of = 6.6×10^−2 1×10^−3 .

the average volume of a cookie; 4.12 cm^3
ratio of the diameter to the thickness: 135
A)Find the uncertainty in the volume of a cookie.
B) find the uncertainty in this ratio.
