Question

Find the circumference of the object. Use $3.14$ or $\frac{22}{7}$ for $\mathrm{\pi }$.

Answer 1

Given: Diameter of the object (d) = $6$ cm.

We know that the circumference of a circle is $\mathrm{\pi }$ times its diameter.

Circumference = $\mathrm{\pi }$d

$\Rightarrow$Circumference = $3.14\times 6$ [Since, $\mathrm{\pi }=3.14$]

$\therefore$Circumference = $18.84$ cm

Hence, the circumference of the given object is $18.84$ cm.
