Answer 2

Answer:

24.5 cm

Step-by-step explanation:

Given Circumference = 154 cm .

By formula :

we know that : C = 2 π r

So : 2 π r = 154 cm

⇒ 2 π r = 154 cm

⇒ 2 × 22/7 × r = 154 cm

⇒ 44/7 × r = 154 cm

⇒ r = 154 × 7/44 cm

⇒ r = 7 × 7/2 cm

⇒ r = 49/2 cm

⇒ r = 24.5 cm

Hence the radius is 24.5 cm
