Answer: 
Step-by-step explanation:
You need to use the following formula:
Where "r" is the radius and 
is is the central angle of the arc in radians.
Assuming that that the angle 
is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.
Therefore, you get:
It would be 0.35 because you need to multiply by 5 and then move the decimal 2 spaces to the right.
I think it is"A" hope it help
The table represents a greater unit rate of change.
If AC=BD, than Quad ABCD is a rectangle
AC
√(3+3)²+(6-1)²
√6²+5²
√36+25
√61
BD
√(1+1)²+(2-7)²
√2²+(-5)²
√4+25
√29
Quad ABCD is not a rectangle because √61 and √29 are not equal.
