It is A because the radius is 10 which means that if x=0 then y must equal 10. (0,5) would be inside of the circle. If this doesn't make sense graph the circle and the points and you'll see what I mean.
Answer: 11
Step-by-step explanation:
Since the equation of circumference is 2(r)pi
if 22pi=2(r)pi
then 22=2r
22=2r
r=11
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
Answer:
885735
Step-by-step explanation:
Each number is being multiplied by 3
5, 15, 45, 135, 405, 1215, 3645, 10935, 32805, 98415, 295245, 885735
-(3*8)+6=-18
the water level decreased by 18 inches.
