A barrel of tomato sauce has spilled on a tile floor. The sauce flow can be expressed with the function r(t) = 2t, where t represents time in minutes and r represents how far the sauce is spreading. The spilled sauce 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 sauce as a function of time, or A[r(t)]. Show your work. (6 points) Part B: How large is the area of spilled sauce after 5 minutes? You may use 3.14 to approximate π in this problem. (4 points)

A = πr² and r = 2t. How do you write A in terms of t without an r?

\[A = \pi(2t)^2\]

Oh ok :]

then just plug in 5 for t to get the area
anonymous
  • anonymous
So, \[\pi \left( 2 *5 \right)^{2}?\]
