Acarton of milk has spilled on a tile floor. the milk flow can be expressed with the function m(t) = 9t, where t represents time in minutes and m represents how far the milk is spreading.

the flowing milk is creating a circular pattern on the tile. the area of the pattern can be expressed as a(m) = πm2.

part a: find the area of the circle of spilled milk as a function of time, or a[m(t)]. show your work. (6 points)

part b: how large is the area of spilled milk after 2 minutes? you may use 3.14 to approximate π in this problem. (4 points)
