Due to a lightning strike, a forest fire begins to burn and is spreading outward in a shape that is roughly circular. the radius of the circle is modeled by the function r(t) = 2t + 1, where t is the time in minutes and r is measured in meters.
1). write a function for the area burned by the fire directly as a function of t by computing (a ◦ r)(t).
2) find the area of the circular burn after 20 minutes.
