Circumfrence is to a circle as perimeter is to a polygon. The circumfrence of a circle always equals the diameter (or two times the radius, since the radius is half of the diameter) times pi.
The circumfrence would be 7926.41π miles because of this.
Should you round pi to 3.14, the circumfrence would be 7926.41 * 3.14.
This is equal to <span>24888.9274 miles. (round that if needed)</span>
Using the y=mx+b format,
m the slope = (5--9)/(8--12) = 14/20 = 7/10=0.7
y-y1 = m(x-x1)
y-5 = .7(x-8) = .7x-5.6
y = .7x +0.6
10y = 7x + 6
so 7x - 1y = -6 any your equation is almost correct.
Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5
