Question

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

Answer 1

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
