Question:

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.

Answer:

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.
