Answer:
88 cm
Step by step explanation:
Circumference = 2πr
Circumference of first concentric triangle=
2×22/7×8
= 44/7×8
=50.285714
Circumference of second concentric triangle=
2×22/7×22
= 44/7×22
=138.285714
Difference = 138.285714 -50.285714
=88
Hence difference between their circumference is 88.
