(a) Using a ruler and a pair of compass only;
construct triangle PQR such that |PR| = 8cm, |PQ| = 6cm and |QR| = 5cm;
construct the perpendicular bisector of PR and label it l1
construct the perpendicular bisector of QR and label it l2;
Label the point of intersection of l1 and l2 as N
With N as centre and radius equal to |PN|, draw a circle.
(b) (i) Measure the radius of the circle.
(ii) Calculate the circumference of the circle, correct to 3 significant figures.
[Take π = 3.14]
