Answer :

The perimeter of the circle formed is 6.28(x+1).

Step-by-step explanation :

Given,

Radius of circle = x

Old diameter = 2x

Now, according to question

New diameter = Old diameter + 2 units

[since the diameter is increased by 2 units]

New diameter = 2x+2

Now, Perimeter of circle

2\pi r

\pi d [since, 2r=d ]

3.14\times (2x+2)

6.28x+6.28

6.28(x+1)
