Answer 1

2.

OPD is a right angle triangle.

By Pythagoras theorem,

(OD) ² = (OP)² + (PD)²

(25)² = (OP)² + (14)²

(OP)² = 625 - 196

(OP)² = 429

OP = 20.71 cm

3.

Construction: Join OA.

Let a segment from center intersects AB at P.

By Pythagoras theorem,

(OA)² = (AP)² + (OP)²

(OA)² = (12)² + (9)²

(OA)² = 144 + 81

(OA)² = 225

OA = 15 cm
