Question

A 35-mm camera allows you to control the diameter d of the aperture by changing the f-stop, which varies inversely with the diameter according to the formula f

.

a. If f, find the diameter.

b. If the is , by what factor will the change?

c. The radius r is one-half of the diameter. Describe the proportional relationship between the radius and the diameter.

d. Area A is proportional to the radius squared according to the equation Ar. What is the equation that relates area and diameter?

e. What is the equation that relates area and f-stop?
