BRAINLIST IS IMPORTANT FOR ME !

Step-by-step explanation:

Let the radius of required circle = r cm

Let the radius of required circle = r cmRadius of 1st circle = 9 cm

Let the radius of required circle = r cmRadius of 1st circle = 9 cmRadius of 2nd circle r2 = 19 cm

Let the radius of required circle = r cmRadius of 1st circle = 9 cmRadius of 2nd circle r2 = 19 cmAs per the question

Let the radius of required circle = r cmRadius of 1st circle = 9 cmRadius of 2nd circle r2 = 19 cmAs per the questionCircumference of the required circle = circumference of two circles

Let the radius of required circle = r cmRadius of 1st circle = 9 cmRadius of 2nd circle r2 = 19 cmAs per the questionCircumference of the required circle = circumference of two circlesCircumference of small circle 2rr1

Let the radius of required circle = r cmRadius of 1st circle = 9 cmRadius of 2nd circle r2 = 19 cmAs per the questionCircumference of the required circle = circumference of two circlesCircumference of small circle 2rr1= 2 X 9

= 18T

= 18TCircumference of small circle = 2tr2

= 18TCircumference of small circle = 2tr2= 2T X 19

= 18TCircumference of small circle = 2tr2= 2T X 19= 38T

Now,

Now,Circumference of the required circle = Sum circumference of two circles

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T2Tr = 58T

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T2Tr = 58T56T r =

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T2Tr = 58T56T r =21

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T2Tr = 58T56T r =21r = 28 cm

Now,Circumference of the required circle = Sum circumference of two circles2Tr = 18T + 38T2Tr = 58T56T r =21r = 28 cmHence, radius of new circle is 28 cm.
