Answer:
Radius of the circle = 119
Step-by-step explanation:
here's the solution :-
we know that the perpendicular from centre to any chord bisects the chord so,
=》AT = 1/2 × OT
=》AT = 1/2 × 210
=》AT = 105
now, join VT ( by construction )
so, triangle VTA is a right angled triangle, with right angle on A.
now, by pythagorous theorem,
=》VT^2 = VA^2 + AT^2
=》VT^2 = (56)^2 + (105)^2
=》VT^2 = 3136 + 11025
=》VT =

=》VT = 119
and VT joins the centre of the circle with the circumference, hence VT is the radius of the circle .
