Question

5. A wire of length 308 cm is bent to form a circle.
Find the diameter of the circle so formed.​

Answer 1

Answer:

• Diameter of circle formed = 98 cm.

Step-by-step explanation:

Given:

Length of wire = 308 cm

To Find:

Diameter of circle formed

So, we know that when circle formed length changed into circumference of circle.

So, Circumference of circle = 308 cm

We, know that

⇒ Circumference of circle = 2πr

⇒ 308 = 2 × 3.14 × r

⇒ 308 = 6.28r

⇒ r = 308/6.28

⇒ r = 49 cm (Approx)

So, Diameter = 2r = 98 cm.

Hence, Diameter of circle formed = 98 cm.
