Question

circumference 616 cm what will be the diameter and radius​

Answer 1

Answer:

Given :-

• Circumference of circle = 616 cm²

To Find :-

• Diameter
• Radius

Knowledge Required :-

Circumference = 2πr

Diameter = 2r

Solution :-

616 = 2×22/7 × r

616 = 44/7 × r

r = 616 ÷ 44/7

r = 616 × 7/44

r = 14 × 7

r = 98 cm

Now,

Diameter = 2r

Diameter = 2(98)

Diameter = 196 cm

Answer 2

Given:-

• Circumference of the circle is 616cm.

To Find:-

• Find the diameter and radius.

Concept:-

• Let's go through the concept first. Concept used here is Circumference of a Circle.Susbstitute the given values in the equation and solve it.

Formulae Applied:-

• Circumference of a Circle = 2πr

Solution:-

Circumference of the circle = 616cm

Radius = ??

Diameter = ??

According to the question we have!

Circumference of a Circle = 2πr

⟹ 2πr

⟹ 2πr = 616

⟹ 2 × 22/7 × r = 616

⟹ r = 616 × 7/2 × 22

⟹ r = 98

⟹ r = 98cm

Hence,

The radius of the circle is 98cm.

Now,

Diameter = Radius × 2

⟹ Radius × 2

⟹ 98 × 2

⟹ 196

⟹ 196cm

Hence,

The diameter of the circle is 196cm.
