Answer:The equation relating I, r, and k is I =K/r²

Explanation:

The intensity, I, of a sound varies inversely with the square of the distance, r, from the source of the sound can be written as

I ∝ 1/r²

Introducing the constant of proportionality, K we have that

I =K x 1/r²

Therefore , the equation relating I, r, and k is I =K/r²
