Find the circumference of this circle
using 3 for 7
C [?]
1
C = 27

Answer 1

`6.283185307`

Explanation:

`Formula - C = 2\pi r`

`Formula = 2*\pi*1 = 6.283185307`

Answer 2

C≈6

Explanation:

remember circumference formula

`\displaystyle C = 2\pi r`

given that,r=1 thus substitute:

`\displaystyle C = 2\pi .1`

simplify mutilation:

`\displaystyle C = 2\pi`

substitute the given value of π:

`\displaystyle C = 2.3`

simplify multiplication:

`\displaystyle C = 6`

and we are done!
