C = 2πr
C = 2(3.14)(0.8)
C = 2(2.512)
C = 5.024 m
The answer is C.
Answer:
x = 13
Step-by-step explanation:
First start with the blank equation

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

Then solve
25 + 144 = 
169 =

c = 13
Let us cross multiply.
5/9=10/x
9 x 10= 5x
90=5x
90 <u />÷ 5= 5x <span>÷ 5
18=x
So, the answer is 18. I hope this helped you, since I just learned cross multiplication last week.</span>
