Step-by-step explanation:

Question :

If circumference of a circle is 176 cm , find its radius

Answer :

★ Circumference of circle = 176cm

★ formula of circumference = 2πr

2πr = 176cm

❝let the radius be X ❞

⇛ 2×22/7× X = 176cm

⇛ 44/7×x = 176cm

⇛ X = 176cm × 7/44

⇛ X = 28cm

Hence, the radius of circle is 28cm
