Answer:

Chord:PN , AB

Radius:OA,OB,ON

Answer 2

Answer:

1). chords are those lines which cross a circle on two points... the diameter of a circle devides a circle onto two equal chords both having 180°

here, CHORD AB, CHORD PN and CHORD MN are chords of circle.

2). RADII is the line which joins the Centre of a circle with any point on the circumference of the circle.

here, OM, OB, OA are radii of the circle.

Step-by-step explanation:

Formulae for circle:

D=2*R, where R is radius and D is diameter of circle.

C= 2*π**R. where C is the circumference and R is radius.

area of circle= π*R*R.
