Answer:

15.71

Step-by-step explanation:

To find the radius, half the diameter because r x 2 = diameter. 5/2 = 2.5

Put in circumference formula C=2πr

c=2 x 3.14 x 2.5

c= 2 x 7.85

c=15.7

The graph below shows the distances, in miles, that a dragonfly can travel in a certain number of hour. Based on the graph, what
Evgen [1.6K]
The graph provides distance as a linear function of time.
The y-intercept is zero.

The line passes through (0,0) and (6,120).
Calculate the slope.
m = (120 - 0)/(6 - 0) = 20

The equation of the line is
d = 20t
where
t = time, hours
d =  distance, miles

Therefore distance is the dependent variable.
When t = 24 hours, the distance is 20*24 = 480 miles.

Answers:
(a) Distance is the dependent variable
(b)The equation relating the two variables is
    d = 20t
    where
    t = time, hours
    d = distance, miles
(c) In 24 hours, the dragonfly will travel 480 miles.
