Question

1 point
Q9. The length of a tangent PQ, from
the external point P, is 24 cm. If the
distance of the point P, from
thecentre, is 25 cm. What is the radius
of the circle?
O a) 3 cm
O (b) 4 cm
O (c)
5
cm
(d) 7 cm​

Answer 1

Answer:

Answer:14cm

Steps:let the centre be o

Tangent (pq ), segment (op) and radius (qo) form a right triangle

Thus by by Pythagoras theorem r^2=25^2+24^2

r=7

Now:

Diameter=2r=14cm

Step-by-step explanation:

Answer 2

Answer:7cm

Step-by-step explanation:radius =√25×25-24×24

=√625-576

=√49

=7
