Question

The radii of two circles are 8 cm and 6 cm respectively. Find the radius of the circle
having area equal to the sum of the areas of these two circles

Answer 1

Let the radius of required circle is r cm. 

So, πr2=πr12+πr22

r2=r12+r22

r2=(8)2+(6)2

r2=100

r=10cm

Answer 2

Answer:

bhai kuch dhanka puch lay

mara sar durd ho raha ha

area of first circle = 64 pi

area of second circle = 36 pi

pi R square =64 pi + 36 pi

r= 100 r= root 100

r = 10 m
