Answer:
C) 314 feet.
Step-by-step explanation:
We have been given that a circular track is 100 feet across. We are asked to find the distance around the track.
The distance around the track would be equal to circumference of circle.
, where r represents radius of circle.
Since we have been given across distance, so it will be diameter of track.
To find radius we will divide across distance by 2.
Upon substituting our given values in circumference formula, we will get:
Therefore, the distance around the track is 314 feet and option C is the correct choice.
Answer:
54
Step-by-step explanation:
The circumcenter is the middle to each vertex. So since they gave you 9 in. and you have to go back and forth on each line, that is 18 in. per line. Considering there are three lines, add all of them together (Or multiple 18 by 3) to get 54 in.

4/3 or 1 1/3 servings
Step-by-step explanation:
3 1/3×0.4 = 1 1/3 or 4/3
hope this helped! :)
Check the picture below.
so hmmm for the sake of completion, let's check where they intersect
now, notice, in the picture the function that is "above" or the "ceiling" function is the sin(x), so we'll get the area under the curve by using "above" - "below" functions.
now let's use the triple angle identity of sine
