Question

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

Answer 1

Answer:

The radii of two circles are 8 cm and 6 cm respectively. Find the radius of the circle having its area equal to the sum of the areas of the two circles. Let the radius of the required circle be R and radii of two given circles be r1 and r2, then according to question. ⇒ R = 10 cm.

Step-by-step explanation:

The radii of two circles are 8 cm and 6 cm respectively. Find the radius of the circle having its area equal to the sum of the areas of the two circles. Let the radius of the required circle be R and radii of two given circles be r1 and r2, then according to question. ⇒ R = 10 cm.

Answer 2

Answer:

10 cm

Step-by-step explanation:

Let the radius of required circle is r cm.

So, πr 2 =ππr +πr 2

r²=r1 +r 2

r² =(8)²+(6)²

r²=100

r=10cm
