Question

what is the circumference of the circle if the radius is increased by 2.5cm?

Answer 1

circumference is 2πr
=2×3.14×2.5
=15.7cm

Answer 2

The circumference of the circle if the radius is increased by 2.5cm is

15.7cm

step-by-step explanation:

Given:

• Radius $=2.5cm$

To find:

• To find the circumference of the circle if the radius is increased by 2.5cm.

Formula used:

Circumference of the Circle $=2\pi r$

solution:

We know that the value of $\pi$ is $3.14$

$C=2$ × $3.14$ × $2.5$

$C=15.7cm$

hence, the circumference of the circle is $15.7cm$.
