Area of a semicircle =

r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
Answer:
the answer is A (x + 5, y +10)
Step-by-step explanation:
you gotta go up 10 units then add (the right direction) by 5 units
we have given that 
where
represents the number of elements in C.
where we have 4 and 6 which have two elements.
so 
X= -12 and that’s you answer
