Acontainer of oil has spilled on a concrete floor. the oil flow can be expressed with the function n(t) = 7t, where t represents time in minutes and n represents how far the oil is spreading.

the flowing oil is creating a circular pattern on the concrete. the area of the pattern can be expressed as a(n) = πn2.

part a: find the area of the circle of spilled oil as a function of time, or a[n(t)]. show your work. (6 points)

part b: how large is the area of spilled oil after 8 minutes? you may use 3.14 to approximate π in this problem. (4 points)

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
