Question

Find the diameter of a circle whose circumference is 23.326km​

Answer 1

${ \huge{ \underline{ \underline{ \sf{ \green{GivEn : }}}}}}$

• Circumstance of circle = 23.326km

${ \huge{ \underline{ \underline{ \sf{ \green{To \: find :}}}}}}$

• What's the diameter of circle?

Formula to be used :-

• Circumference of circle = 2πr

• Diameter = 2× Radius

${ \huge{ \underline{ \underline{ \sf{ \green{SoluTion : }}}}}}$

Given that,

Circumstance of circle = 23.326km

A.T.Q :-

Circumference of circle = 23.326

2 × 3.1416 × r = 23.326

6.2832 × r = 23.326

r = 3.7

_________________________________________________

Now, find diameter

We know that,

Diameter = 2× Radius

Put the value of r ( Radius)

Diameter = 2 × 3.7

Diameter = 7. 4

Hence,

Diameter of circle = 7.4km.
