An artist’s canvas has sides measuring 3x – 3 and 4x + 1 inches.

What is the area of the canvas? Show all work.


The artist laid the canvas flat on the floor and poured some paint in the center. The paint flows at a rate of r(t) = 4t where t represents time in minutes and r represents how far the paint is spreading on the canvas. The area of the paint can be expressed as A[r(t)]= πr². What is the area of the circle created by the paint?


If the artist wants the circle to be at least 1300 in², will it be that large in 5 minutes? Support your answer with your work.
