Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p 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(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.

A(p(t)) =113.04 t^2
A (p(8)) =7234.56
Step-by-step explanation:
p(t) = 6t
A (p) = 3.14 p^2
So A(p(t)) = means we put p(t) in the function for A
= 3.14 p^2
= 3.14 (6t) ^2
= 3.14 (36t^2)
A(p(t)) =113.04 t^2
Let t=8
A (p(8)) = 113.04 (8)^2
= 113.04(64)
=7234.56
