radius of first circle = 20 cm
circumference = 2pie r
=2*22/7*20
=125.71 cm
radius of second circle = 13 cm
circumference = 2 pie r
2*22/7*13
81.71
difference = 125.71 - 81.71
= 44 cm
circumference = 2pie r
=2*22/7*20
=125.71 cm
radius of second circle = 13 cm
circumference = 2 pie r
2*22/7*13
81.71
difference = 125.71 - 81.71
