If (m, 2) is on a circle with center (−3, 2) and radius 8, what is a value of m?
Answers: 1
![\bf \textit{we know the distance from m,2 and -3,2(center) is the radius} \\\\\\ d=8\implies 8=\sqrt{[m-(-3)]^2+[2-2]^2} \\\\\\ 8=\sqrt{(m+3)^2+(0)^2}\implies 8=\sqrt{(m+3)^2}\implies 8^2=(m+3)^2 \\\\\\ 64=(m+3)^2\implies \sqrt{64}=\sqrt{(m+3)^2}\implies 8=m+3 \\\\\\ 8-3=m](/tpl/images/0462/5377/2d492.png)
