Question

Find the circumference of a circle whose radius is 12 metre

Answer 1

Answer:

2πr

Step-by-step explanation:

2*22*12/7=528/7=75.428

Answer 2

The circumference of a circle is "75.4286 metre".

Step-by-step explanation:

Given,

The radius of a circle (r) = 12 metre

To find, the circumference of a circle = ?

We know that,

The circumference of a circle = $2\pi r$

= $2\times \dfrac{22}{7} \times 12$ metre

= $\dfrac{44\times 12}{7}$ metre

= $\dfrac{528}{7}$ metre

= 75.4286 metre

∴ The circumference of a circle = 75.4286 metre

Thus, the circumference of a circle is "75.4286 metre".
