Answer 1

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 =

$\sqrt{14161}$

=》VT = 119

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