Question

the radius of the circle whose circumference is equal to the sum of the circumferences of the two circles of radii 24 cm and 7 cm is​

Answer 1

Answer:

31 cm

Step-by-step explanation:

Let the new radius be R.

So,

2 × 22/7 × 7 + 2 × 22/7 × 24 = 2 × 22/7 × R

44 / 7 × (24 + 7) = 44/7 × R

R = 31 cm
