Question

Ajay traveled along a path which was straight up to 10 m (from point P to point T) and then went along an arc of a circle (from point T to point B) to reach his destination (B). Path PT is tangent to the circle at point T. If Ajay had travelled along the straight line joining his starting point P and his destination point B, he would have traveled 20 m and would have passed through the centre of the circle to which the arc belongs. The radius of the circle is(to which arc TB belongs) ___ m.

Answer:
:

Ajay Traveled Along A Path Which Was Straight Up To 10 M (fr...

Letrbe the radius of the circle of which the arc is a part.

∵

PT

^{2}

= PA × PB

∴

100 = (20 - 2r) × 20

∴

40r= 400 − 100

∴

r= 7.5 m
