Question

three circles each of radius cm are drawn in such a way that each of their touches the other two. find the area enclosed between the circle ​

Answer 1

Step-by-step explanation:

HEY MATE ..

Given, A,B and C are the centres of three circles touching each other at P,Q& R.

All the circles have equal radii

r=3.5 cm.

.

To find out: The area enclosed by the circles.

Solution:We join AB,BC and CA. Since AB joins the centres of two circles touching each other,

we have AB= sum of their radii

=2r=2×3.5 cm =7 cm.

Similarly BC=7 cm and CA=7 cm.∴

ΔABC is equilateral with sides =a=7 cm.
