Question

x is the radius of the circle, if the diameter increased by 2 units , then write the perimeter of circle in the formnof x

Answer 1

$\mathfrak{\huge{Answer:}}$

Given is the radius of the circle = x

And the condition given to us is that the diameter is increased by 2 units. In the algebraic form, it means that :

New Diameter = Old Diameter + 2 units

We know that the diameter = 2 radius

=》 The Old Diameter will be = 2x

=》 The New Diameter will be = 2x + 2

We know that the perimeter of a circle = Circumference of the circle = $\tt{2 \pi r}$ = $\tt{\pi d}$

Circumference = $\tt{\pi \times (2x + 2)}$ units

Circumference = $\tt{3.14 \times (2x + 2)}$ units

Circumference = $\tt{6.28x + 3.14}$ units

That's the answer!
