-3 should be the solution.
Step-by-step explanation:
every point on the circle has the same distance from the center : r (radius).
we can see that radius right there on the x-axis : the distance of (3, 0) to (0, 0) is simply 3. that is our radius.
the distance formula is applied Pythagoras
distance² = (difference in x coordinates)² +
+ (difference in y coordinates)²
distance = sqrt( ... )
so,
(-2.5, - 2.5)
(-2.5 - 0)² + (-2.5 - 0)² = 6.25 + 6.25 = 12.5
that is not 3² = 9, so the point is NOT on the circle.
(1, 3)
(1 - 0)² + (3 - 0)² = 1 + 9 = 10
that is not 3² = 9, so the point is NOT on the circle.
(2, -sqrt(5))
(2 - 0)² + (-sqrt(5) - 0)² = 4 + 5 = 9
that IS 3² = 9, so, the point IS on the circle.
(-sqrt(3), -sqrt(7))
(-sqrt(3) - 0)² + (-sqrt(7) - 0)² = 3 + 7 = 10
that is not 3² = 9, so the point is NOT on the circle.

the statement is correct
Answer:
Length of the flag is 190 feet and width of the flag is 80 feet.
Step-by-step explanation:
Given:
Perimeter of the flag = 540 feet
We need to find the length and width of the flag.
Let the length of flag be 'l'.
Let the width of the flag be 'w'.
Now given:
length is 110 feet greater than the width
Length of the flag
Now we know that,
Flag is in rectangular shape.
So Perimeter of rectangle is given by 2 times sum of length and width.
framing in equation form we get;
Now dividing both side by 2 we get;
Now Substituting the value of 'l' in above equation we get;
Subtracting both side by 110 we get;
Dividing both side by 2 we get;
Width = 80 feet
Length
Hence Length of the flag is 190 feet and width of the flag is 80 feet.
