Question

The diameter of a circle is 24 cm. Find its radius. If O is the centre of the circle, state,
giving reasons, the position of points P, Q and R, if (i) OP = 18 cm, (ii) OQ = 12 cm.
​

Answer 1

Answer:

$\bold\red{Radius=12\:cm}$

$\bold\red{P\:is\:outside\:the\:circle}$

$\bold\red{Q\:is\:on\:the\: circumference}$

Step-by-step explanation:

Given,

A circle having centre O

The length of diameter is 24 cm

Now,

we know that,

Radius is half of the diameter length.

Therefore,

we get,

Radius = 12 cm

Now,

(i) OP = 18 cm

Since OP is greater than Radius.

Therefore,

P lies outside the circle.

Again,

(ii) OQ = 12 cm

The length of OQ is equal to the length of radius.

Therefore,

Q lies on the circumference of the circle.
