x is the radius of the circle, if the diameter increased by 2 units, then write the perimeter of circle in the form of x.
Circumference = 6.28x + 3.14
Perimeter = Diameter of circle.
= 2πr
= 3.14 × 2x + 2
= 6.28x + 3.14

Step-by-step explanation:
The Perimeter/Circumference of the circle in the form of x = 6.28x + 6.28 unit.
Step by step solution:
Radius of circle = x
Diameter of circle = Double of radius = 2x
According to the question,
The diameter is increased by 2 units.
So,
The new diameter = 2x + 2
Perimeter/Circumference of the circle = 2πr
= π × (new diameter)
= π(2x + 2)
= 3.14(2x + 2)
= 6.28x + 6.28
Therefore, the Perimeter/Circumference of the circle in the form of x = 6.28x + 6.28 unit.
