Answer:
Roberta will jog 13 laps on the sixth day.
Step-by-step explanation:
In the pattern 3, 5, 7 we can see it is adding 2 each day.
Keep adding 2 until you get to 13, which is the sixth day.
The answer is
-2(u+3)-5u
-2u-6-5u
-3u-6
"Formula of a circle" is too vague to be meaningful. Perhaps you meant, "Formula for the area of a circle in terms of its circumference."
The area of a circle in terms of its radius is A = πr^2. To put this formula to use, we have to know the radius of the circle. The circumference of a circle in terms of its radius is C = 2πr, so a formula for the radius is r = C / (2π).
Now let's find a formula for the area of a circle in terms of its circumference:
C C^2
A = πr^2 = π { ---------------- }^2 = ------------
2π 4π
or:
A = (C^2) / 4π
