Answer:
Radius of 1 st circle = 20 cm
Circumference of the circle = 2\pi r2πr
= 2\times\frac{22}{7}\times202×722×20
= \frac{880}{7}=122.8\ cm7880=122.8 cm
Radius of 2nd circle = 13 cm
Circumfernce of the circle = 2\pi r2πr
=2\times\frac{22}{7}\times13=\frac{572}{7}=81.7=2×722×13=7572=81.7
Difference of circumfernce of two circles
= 122.8 - 81.7 = 41.1 cm
