Let r1 = 20 cm and r2 = 13 cm.
Let C1 = the circumference if the first circle and C2 = the circumference of the second circle
C1 = 2 π r1
C2 = 2 π r2
C1 - C2 = 2 π r1 - 2 π r2
= 2 π ( r1 - r2)
= 2 π ( 20 - 13) cm
= 2 × 22/7 × 7 cm
= 44 cm
Ans. = The difference between the circumference of both the circles is 44 cm.
Hope it helps!! ^^
