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) = $7$ inches

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

Circumference of circle = $\mathrm{\pi d}$

= $\frac{22}{7}\times 7$ [Since, $\mathrm{\pi }=\frac{22}{7}$]

= $22$ inches

Hence, the circumference of the given object is 22 inches.
