the answer is 3.279604223
C = 2πr
17 = 2(3.14)(r)
17 = 2(3.14r)
17 = 6.28r
6.28 6.28
2.71 ≈ r

we know that
If two <u>lines</u> are <u>perpendicular</u>, then the product of their <u>slope</u> is equal to minus one
so
If two <u>lines</u> are <u>parallel</u>, then their <u>slope</u> are equal
In this problem we have
--------> <u>linear equation</u> A
the <u>slope</u> is
--------> <u>linear equation</u> B
the <u>slope</u> is
Find the product
---------> the <u>lines</u> are <u>perpendicular</u>
therefore
the answer is the option B
Perpendicular
