A fire has started in a dry, open field and is burning in a circular area with an initial radius of 3 feet. The radius
of the fire is increasing at a rate of 2 ft/min. es
The area of a circle is given by the formula:
A = ar
Define a function, g, which relates the size of the radius (r), measured in centimeters, in terms of the number
of seconds (t) since the radius of the fire began increasing.

answer choices:

g(r)= 2r+3
g(r) 3r+2
g(t)= 2t+3
g(t) = 3t+2
