TanY=y/x
cotY=1/tanY
cotY=x/y
It’s for sure B the formula for circumference is
Pi times the diameter and the diameter is double the radius so it’s pi multiplied by 8
3, 217
Sorry if it’s wrong
Hope this helped *smiles*
<h3>First part of the problem:</h3><h3>-y - 4 = 4x</h3><h3> + 4 + 4</h3><h3>-y + 0 = 4x + 4</h3><h3> -y = 4x + 4</h3><h3 />
Hope this helps!
