Prove that: The points \( A(3,-1) \), \( B(4,6) \) and \( C(2,-2) \) are located on a circle whose centre is \( M(-1,2) \), then find the circumference of the circle where \( \pi = 3.14 \).
\( \because MA = MB = MC \)
\( \therefore A, B \) and \( C \) lie on the circle \( M \) which its radius length is 5 length units
\[ \text{Circumference} = 31.4 \text{ length units} \]
\( \therefore A, B \) and \( C \) lie on the circle \( M \) which its radius length is 5 length units
\[ \text{Circumference} = 31.4 \text{ length units} \]
