The circumference of a circle is found with the equation
C = 2 pi * r
Since we have the circumference we can find the radius. Then once we have the radius we can determine the diameter.
9619 = 2 (22/7) r
multiply each side by 7
67333 = 2*22*r
67333 = 44r
divide each side by 44
r = 67333/44 = 1530.295 rounded to the nearest hundredth = 1530.30
The diameter is 2 x the radius, so
1530.30 x 2 = 3060.6 ft
The diameter of the crater is 3060.6 ft

Okay so whats the question? That is just a statement
The answer is C. $910, all you do is take the income and divide it by the number of months to find the average.
Well because there's and equal amount on each of the 8 pages, you'd do 128/8 which will show that there's 16 stamps per page.
