Question

8Q If area of circle is equal to it's circumference then radius of that circle will be



1

2

3

4

​

Answer 1

Answer:

hope it helps

Step-by-step explanation:

2pie r = pie r^2

bringing pie r to rhs

2= pie r^2/pie r

we get r=2

Answer 2

AnSwer -:

Radius of circle = 2

Step by Step Explanation-:


Circumference of a circle-:

“C = 2 πr”

Area of circle =

“A = πr^2”


Here,

C = Circumference

A = Area

R = Radius

π = 22/7 or 3.14

Given ,

If Area of circle = Circumference of circle

To find,

Radius of a circle

_____________________________

Solution-:

Area of circle = πr^2

Circumference of a circle-: 2 πr

Then ,

According to the question,

= 2 πr = πr^2

[ We can eliminate π on both side ]

= 2r = r ^2

= r ^2 = 2r

= r = 2r/r

= r = 2

Radius of circle = 2

Formulas -:


Circumference of a circle-:

“C = 2 πr”

Area of circle =

“A = πr^2”

Radius of circle = d/2

Diameter of circle = 2 x r

Here,

C = Circumference

A = Area

R = Radius

π = 22/7 or 3.14

D = Diameter
