Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(r) = πr2. part a: find the area of the circle of spilled paint as a function of time, or a[r(t)]. show your work. part b: how large is the area of spilled paint after 10 minutes? you may use 3.14 to approximate π in this problem.
