Answer:
Technically, we do not know what x and y are, but there are some numbers that we can assume they stand for. For example, IF x = 10 and f = 1, that would mean the equation is basically 10 - 5 = 5. However, it could be multiple things, such as 20 - 15.
I want the phone so your answer is simple
7+4+4= 15
15-4=11
you answer is 11:4

Answer:
30.25 pi
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
11 pi = 2 * pi *r
divide each side by 2 pi
11/2 = 2 ( pi) * r/ ( 2pi)
11/2 = r
We can find the area by
A = pi * r^2
= pi ( 11/2) ^2
= pi ( 121/4)
= pi ( 121/4)
= 30.25 pi
