Question

Find the circumference of a circle with diameter 2 cm. Use 3.14 for​

Answer 1

6.28

Explanation:

radius= diameter/2

r=2/2=1

circumference formula=2
`\pi`r

`\pi`=22/7 or 3.14

So,

2
`\pi`r= 2*3.14*1= 6.28

Answer 2

6.28 cm

Explanation:

Given,

Diameter = 2 cm

pi = 3.14

To find : Circumference ( circle ) = ?

Radius ( r )

= Diameter / 2

= 2 / 2

= 1 cm

Formula : -

Circumference ( circle ) = 2 pi r

2 pi 4

= 2 × 3.14 × 1

= 6.28 cm
