The radius is 8
Im not sure if this is what your looking for
Answer:
Step-by-step explanation:
To find the distance, we can use the distance formula:
when the given points are 
and 
Plug in the points (-6.25,5) and (-3.75,2)
Therefore, the distance between the two coordinates is , or approximately 3.91.
I hope this helps!
Answer:
The first one
Step-by-step explanation:
the X values are all diffrent
Answer:
D. 1.3
Step-by-step explanation:
5(1.3) = 6.5
Since the value of r is .2 less than b, b would be 1.5
2(1.5) = 3
6.5+3=9.5
Answer:
21.8
Step-by-step explanation:
hii so basically first we find the area of the 9 by 8 and subtract the area of the semicircles.
area of circles are πr^2, so in this situation
π4^2 which is 16π.
with this, the semicircle which is half a circle would give us
16π/2 which is 8π.
but then, we have two semicircles removed so we would have as an answer:
(9*8)-8π+8π
72-16π
then you would have to round so
16π is around 50.2
so 72-50.2 is 21.8
i hope this helped you <33
