Answer:
r = 28 cm
Step-by-step explanation:
Perimeter = 2πr = 176cm
2πr = 176
2 * 22/7 r = 176
44/7 r = 176
r = 176 * 7/44 (cuts by 11th table)
r = 16 * 7/4 (cuts by 4th table)
r = 4 * 7
r = 28cm
Let's check,
2 * 22/7 * 28 = 176 (cuts by 7th table)
44 * 4 = 176
176 = 176
L. H. S = R. H. S
Hence, verified.
