Hello!
Given that the area of a circle is found by using the formula: A = πr². Also, the circumference of a circle is: C = 2πr.
In order to find the circumference, we need to find the radius first. We can substitute the area into the area formula and solve for r.
25π = πr² (divide both sides by π)
25 = r² (take the square root of both sides)
r = 5
The radius of this circle is 5 units. With the radius, we can find the circumference.
C = 2π(5)
C = 10π, which is equal to about 31.4 units.
Therefore, the circumference of the circle is 10π units.
Answer:
53 Pages a Day
Step-by-step explanation:
25% as a decimal is .25
212*.25=53 pages per day
Use the slope form:
m= (y2-y1)/(x2-x1)
Plug in two sets of points from table 4. (0,9) (2,4)
m= (4-9)/(2-0)
m= -5/2 or -2.5
Do the same for the second table. I can't see it very well, so I am assuming that number under 1 is 5. (0,3) and (1,5)
m= (y2-y1)/(x2-x1)
m= (5-3)/(1-0)
m= 2/1 or 2
I hope this helps!
