Question

What is the distance between `(-6 , (-13 pi)/8 )` and `(9, pi )`?

Answer 1

`sqrt(225+(441pi^2)/64`

Explanation:

We know that, the distance between `A(x_1,y_1)and B(x_2,y_2):`
`d(A,B)=AB=sqrt((x_1-x_2)^2+(y_1-y_2)^2.`
Let, `A(-6,(-13pi)/8)andB(9,pi).`
So, `AB=sqrt((-6-9)^2+((-13pi)/8-pi)^2`
`=sqrt((-15)^2+((-21pi)/8)^2)=sqrt(225+(441pi^2)/64`
