Answer: about 14pi inches
Explanation:
7 * 6.28319 = 43.9823
43.9823 / 3.14159 = 14.0000127324
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
Answer:
I can't see the number line but I assume the fraction would be 6/6
Answer: y = 2x - 20
1. y + 18 = 2(x - 1)
2. y + 18 = 2x - 2
3. y + 20 = 2x
4. y = 2x - 20
