B. 13
12^2 + 5^2 = c^2
169 = c^2
13 = c
please mark as brainliest :D
X = 5
Y = 6
Simply we just compare the two shapes and we can see that 6 decreases to 4..so we would assume the rest would decrease by 2. If we were not so sure we could simply do a^2 + b^2 = c^2 and fill in the numbers
Circumference of the circle
cm
i.e., 
i.e., 
Area of the circle is given by




Therefore, the area of the circle is:

Step-by-step explanation:
As we can see the question given
f(x) is varying accordingly to the interval
<em> f(x) = 2 if 2<x≤4</em>
The value of function is 2 for the interval 2 to 4
and interval is open at x=2 and closed at x = 4
<em> f(x) = x + 3 if 4<x<8</em>
The value of function is x + 3 and it is open at x = 4 and x = 8
<em>f(x) = 2x if x
8</em>
The value of function is 2x for x greater than or equal to 8
