4(2k - 3) + 1 = 8k - 11
8k - 12 + 1 = 8k - 11
8k - 11 = 8k - 11
So, these two equations equal to the same thing.
Glad I could help and gave a fantastic day!
Notice that the two semicircles have a radius of 10/2=5 and that their area is simply the area of a complete circle with a radius of 5. In the center you have a rectangle that is 10 by 8. So the total area is:
A=pr^2+xy
A=25p+80 m^2
A≈158.53 which is:
A≈158.5 m^2 (to the nearest tenth of a m^2)
Answer:

Answer:
Step-by-step explanation:
The circumference 
of circle of radius 
is given by
,
and the diameter 
is 2 times the radius:
.
Therefore, the ratio of the circumference to the diameters is
.
Putting in 
, we get
