Question

plz kar do na yarr It's very important ​

Answer 1

Explanation:

The distance between two parallel tangents of a circle will be equal to its diameter.

Radius = 4.5 cm

So

distance = 2 × radius

= 2 × 4.5

= 9 cm

So the required distance is 9 cm.

Answer 2

Answer:

In the given figure, O is the centre of the circle. Line PT and line QR are two parallel.

tangents to the circle at P and Q, respectively.

angleOPT+ angleOQR = 180 (Sum of adjacent interior angles on the same side of the transversal is supplementary)

POQ is a straight line segment.

PQ is the diameter of the circle.

PQ Distance between the parallel tangents PT and QR = 2 x Radius 2x 4.5 = 9 cm

Thus, the distance between two parallel tangents of the circle is 9 cm.
