Find the area of the circle. Give your answer in terms of x. C= pie over 7

Assuming C stands for Circumference we will assume the circum is pi/7

Therefore x = 1/196pi

Step-by-step explanation:

First find the radius with C = 2  * r * pi

1/7pi = 2 * r * pi

r = (1/7pi)/2pi

r = 1/14

Now for the area we have A = r^2 * pi

A = (1/14)^2 * pi

A = 1/196 * pi

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
