The circumference (C) of a circle is related to its radius (r) by the formula:

C = 2πr

Where π (pi) is approximately 22/7.

Given that the circumference C = 176 cm, we can solve for the radius r:

176 = 2 * (22/7) * r

r = (176 * 7) / (2 * 22)

r = (176 * 7) / 44

r = (4 * 7)

r = 28 cm

Therefore, the radius of the circle is 28 cm.
