Question

The radii of the two circles are 6 cm and 4 cm respectively. Find the radius of the circle having area equal

to the sum of the areas of the two circles.​

Answer 1

Step-by-step explanation:

area of circle = π×r×r

area of (i) circle = 22/ 7 ×6×6

36×22\7 = 113.1cm

area of (ii) circle = π×r×r

22\7×4×4 = 50.2cm
