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 â—¦ r)(t).
2) find the area of the circular burn after 20 minutes.

After the seventh month of a 12-month loan: the numerator is: {(n + 11) + (n + 10) + (n + 9) + (n + 8) + (n + 7) + (n + 6) + (n + 5)} = , and the denominator is: {(n) + (n + 1) + + (n + 11)} = . therefore, the fraction is numerator/denominator (to the nearest tenth) = %
