The answer to the question is b
(√200/√5)= √40= √4*10= 2√10
Answer:
diameter
circumference

diameter
Step-by-step explanation:
First, find the length of the diameter (d) and the length of the circumference of the circle (c).
Next, divide the length of the circumference c by the length of the diameter d and set up an equation

where the ratio equals to
(the definition of
)
Then, solve the equation for the circumference c:

Finally, substitute 2 times the radius for the diameter

(4xy-2y^2)+2y
4-2=2....x will remain y^1-y^2=y^-1
2xy^-1+2y
answer=2x+2y
Answer: 160
Step-by-step explanation:
So first you start by making the percent which is 20 a decimal (.20) . Then , you multiplu .20 by 800 and get 160 , or if you know 10% is 80 2 times that would be 20 percent . And 80 plus 80 is 160 .
