~Hello There!~
The formula to find the area of a circle is:
We already know this answer, so we write it as:
We need to calculate the radius (r) from this so divide both sides by
Square root this to get r
r = 3.949327085
The formula for circumference is
(d is the diameter )
Double the radius to get the diameter:
d = 7.89865417
Multiply this value by to get the answer
The circumference is 24.81435391
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
Proportionality constant =
Step-by-step explanation:
From the graph attached,
Data set representing the relation between seeing lightning and the hearing thunder is,
{(15, 3), (25, 5), (35, 7), (45, 9)}
Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)
d = kt
Here k = proportionality constant
k =
From the data set one point is (15, 3).
k =
k = miles per second
Therefore, proportionality constant is miles per second.
