If PQ is the radius, the that means the circumference is 2\pir, and r = 3, so 2*(3.14)*3 = 18.8

Glad I could help.

Use an equation to find the value of k so that the line that passes through the given slope (1,3) , (5,k) m=2
scoray [572]

Answer:

The value of k with given points and slop = 11

Step-by-step explanation:

Given that a line passes through two points having slop (m) = 2

co ordinates of points are (1 , 3)   and (5 , k)

Now slop of line can be written as,

Slop = \frac{(y2 - y1)}{(x2 - x1)}

Or, m =  \frac{(y2 - y1)}{(x2 - x1)}

     2 =  \frac{(k - 3)}{(5 - 1)}

Or, 2 =  \frac{(k - 3)}{(4)}

So , k - 3 = 8

∴ K = 8+3 = 11

Hence the value of k with given points and slop = 11    Answer
