The distance around a meter is 9619 ft. find the diameter of the crater .use 22/7 for pie
DochEvi [55]
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

Asia and taryn each had the same amount of money. after asia spent $14 and taryn spent $22, the ratio of asia's money to taryn's money was 4 to 3.

Let , initially, they both have $x each .

So according to the given question ,

\frac{x-14}{x-22} = \frac{4}{3}

Cross multiplication

3(x-14) = 4(x-22)&#10;\\&#10;3x-42 = 4x-88&#10;\\&#10;88-42 = 4x-3x&#10;\\&#10;x = 46

Therefore , initially, they both have $46 each .
