Question

What is the distance between `(-7 ,(3 pi)/4 )` and `(2 , (15 pi )/8 )`?

Answer 1

9.67 units (2dp)

Explanation:

To find the distance between 2 points, use the equation

`sqrt(((y_2-y_1)^2)+((x_2-x_1)^2))`

Therefore, `sqrt(((15pi)/8-(3pi)/4)^2+(2+7)^2`

= `sqrt(12.49+81`

=`sqrt(93.49`

=`9.67` units (2dp)
