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

Anarel [89]

Answer:

  • 0.3 or 30%

Step-by-step explanation:

<u>Number of people using more than one sport facility:</u>

  • 38 - gym and pool
  • 31 - pool and track
  • 33 - gym and track
  • 16 - all three

<u>Since 16 is counted for all three, total number of those using more than one facility is therefore:</u>

  • 38 + 31 + 33 - 16*2 = 70

<u>Number of people using exactly one facility is:</u>

  • 100 - 70 = 30

<u>Probability of the person using exactly one facility is:</u>

  • 30/100 = 0.3 or 30%
