The midpoint of the points ( 4, 5.5 ) and ( 4, 10.5 ) is the center of the circle:
C =

C = ( 4, 8 ), h=4, k=8
r =

r = 2.5
The equation of the circle in standard form:
( x - h )² + ( y - k )² = r²
( x - 4 )² + ( y - 8 ) = 6.25
I have a great list that might help you learn some octagon facts!
1. Umbrellas are in the shape of an octagon.
2. As a symbol, octagons symbolize regeneration, infinity, rebirth, and transitions.
3. Octagons are hard to draw...You can find Octagons anywhere if you just look... just kidding only around stop signs. Lol
4. Octagons have eight angles and eight sides.
5. Did you know that you can draw an octagon with just a compass and ruler.
There ya go!
Happy to help. Let me know if you have more questions or any concerns.

Answer:
C
Step-by-step explanation:
A is a horizontal line on 3
B will cross the y axis at (0, -3), and the x axis (3, 0)
D will cross the y axis (0, 1) and the x axis (-0.5, 0)
As C does not have a y-intercept or x-intercept, it will it (0, 0)
Answer: The best estimate for this is 52.

Scientific notation for above value is ~
