Question

a circle of diameter 8 cm is placed in such a manner that its two perpendicular lines then another smaller circle is placed in the cap such that its touch the lions and the circle what is the diameter of the smaller circle ?​

Answer 1

Thus the diameter of the smaller circle is 8 cm.

Step-by-step explanation:

As we know that:

Diameter of circle = 8 cm

The formula of area "A" =  π r^2 ( Since r = d / 2)

A =  π (d/2)^2

Area of bigger circle "A" = =  π (d1/2)^2

Area of smaller circle "A" =  π (d2/2)^2

Now

π (d1/2)^2 = π (d'/2)^2

Taking square root on both sides.

(8 / 2) = d' / 2

4 = d' / 2

4 x 2 = d'

d' = 8 cm

Thus the diameter of the smaller circle is 8 cm.
