Step-by-step explanation:
the circumference of a circle is
C = 2×pi×r
with r being the radius.
the square side length is 22 cm. so, the circumference or perimeter of the square (and therefore the length of the wire) is
4×22 = 88 cm.
now, it is the same wire of the same length that is now forming a circle.
so, the circumference of the square is also the circumference of the circle.
therefore,
88 = 2×pi×r
44 = pi×r
r = 44/pi = 14.00563499... cm
so, rounded, radius = 14 cm.

Answer:
2nd quadrant
Step-by-step explanation:
Reversing the signs of both coordinates reflects the point across the origin. The quadrant diagonally opposite quadrant 4 is quadrant 2.
_____
You recall that quadrants are numbered 1 to 4 counterclockwise, starting from upper right.
Answer:
B 9/10
Step-by-step explanation:
1/5 is equivalent to 2/10.
then just add the numerators.
Answer:
E
Step-by-step explanation:
The ordered pair numbers seemed to big so I guessed and I was right.
3x + 17 - 5x = 12 - (6x+3)
4x + 17 = 9
4x = -8
X = -2
