1 pls 1. A forest fire leaves behind an area of grass burned in an expanding circular pattern.The radius of the circle of burning grass is given by r(t) = 2t +1 where t is the timein minutes and r is in feet.(a) Find a function that gives the area bured as a function of time. Remember,A = Tr?.(b) Find the total area burned after 5 minutes!2. The circumference C of a circle is a function of its radius given by C(r) = 2rr whereC and r are in meters.(a) Express the radius of the circle as a function of the circumference, r(C).(b) Find r(36) and interpret its meaning.

1) The area of a circle is given by: A=πr2...(*) Now, the radius r of the circle of burning grass is…
