Question

the circumference of a circle extends the diameter by 60 cm find the radius of the circle

Answer 1

Answer:

14 cm

Step-by-step explanation:

Let the radius of the circle be r cm.

Then, diameter = 2r cm.

Given that circumference of a circle extends diameter by 60 cm.

∴ Circumference = Diameter + 60

⇒ 2πr = 2r + 60

⇒ 2 * (22/7) * r = 2r + 60

⇒ 44r = 14r + 420

⇒ 30r = 420

⇒ r = 14.

Therefore, radius of the circle = 14 cm.

Hope it helps!
