Answer:
Step-by-step explanation:
Area of a circle is pi r squared.
So 3.142 times the radius squared.
They gave you the diameter(d), that's the distance all the way across. You need the radius(r), which is one half of the diameter. 7 divided by 2.
3.142X3.5squared=
Well, 3.5 squared is 3.5X3.5=12.25
So, then 3.142X12.25=38.4895
Now, we round. Second decimal place is an eight, followed by a nine. Five or above means round up.
38.49
Answer:
Step-by-step explanation:
For this case we have the following parent function:
We apply the following changes:
Shift 2 units left:
This change is the same as writing the function as follows:
Therefore, the new function is:
shift 9 units up:
This transformation is the same as writing the function in the following way:
Therefore, the new function is:

Well, if you run 5 miles in 25 minute you run a mile every 5 minutes. So, there is 190 minutes in 3 hours. So we would need to divide 190 by 5 which is 38. So, the person could run 38 miles in 3 hours.
Answer:
(x+5)² + (y+6)² = 9
Step-by-step explanation:
the equation of a circle is
(x-a)² + (y-b)² = r²
with (a,b) being the center coordinates and r being the radius (half the diameter).
so, in our case here a = -5, b = -6
and r is the distance from the center to any point of the circle. that includes the lowest point asking the edge.
the distance of (-5,-6) to (-5,-9) is 3, as both points have the same x-value, and the only difference is in the y-value.
as we are talking about a distance, negative values don't make sense. so, we need the absolute value of -9 - -6 or then of -3, and that is 3.
