8 ÷ 544 = 0.0147058824, 544 ÷ 8 = 68
Hello there!
First, let's take a look at what the formula for the circumference and area of a circle is.
The circumference is "2

r", or "2 * 3.14 * r".
The area is "

r^2", or "3.14 * r * r".
Let's establish what the radius is, as

is equivalent to 3.14.
The radius is half of the diameter, and our diameter is 10.
Divide 10 by 2 to find our radius.
10 / 2 = 5
The radius is 5.
Now, let's plug in 5 for the radius for both formulas.
C = 2 * 3.14 * 5
10 * 3.14
31.4 is our Circumference.
Now, onto the area.
A = r * r * 3.14
5 * 5 * 3.14
25 * 3.14
78.5 is our Area.
I hope this helps!
Answer:
128
Step-by-step explanation:
You start out with one point on day one. The second day, your points are doubled. Each day after that is doubled from the previous day. So, the second day, you have 2 points. Multiply that by 2 to get 4 for day three.
Day four:4 x 2 = 8.
Day five: 8 x 2 = 16.
Day six: 16 x 2 = 32
Day seven: 32 x 2 = 64
Day eight: 64 x 2 = 128
