Avat of milk has spilled on a tile floor. the milk flow can be expressed with the function r(t) = 4t, where t represents time in minutes and r represents how far the milk is spreading. the spilled milk is creating a circular pattern on the tile. the area of the pattern can be expressed as a(r) = π r^2. part a: find the area of the circle of spilled milk as a function of time, or a[r(t)]. part b: how large is the area of spilled milk after 4 minutes? you may use 3.14 to approximate π in this problem.

Part A:

Setting up the problem: A[r(t)] =  π (4t)^2

= Multiplying: A[r(t)] = 3.14 x 16t^2  

= Solving/  A[r(t)] = 50.24t^2

Part B: Area after 4 min of spilling = t=4

= r (4)= 4x4 =16

= Setting up the problem: A(16) = 3.14 x 16^2

= Multiplying:  A(16)= 3.14 x 256

= Solving/ A(16) = 803.84

= The spilled area of milk after 4 min is 803.84.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
