Question

Find the circumference of a circle that has a diameter of11 / 8 yard. Use 22/7for PI and reduce the fraction to simplest terms.

Answer 1

Given:

Diameter of the circle =

`(11)/(8)\text{ yard}`

Let's find the circumference of the circle.

To find the circumference of the circle, apply the formula:

`C=\pi d`

Where:

π = 22/7

d = 11/8

Thus, we have:

`\begin{gathered} C=(22)/(7)*(11)/(8) \\ \\ C=(22*11)/(7*8) \\ \\ C=(242)/(56) \\ \\ C=(121)/(28)\text{ yards }\approx4(9)/(28)\text{ yards} \end{gathered}`

Therefore, the circumference of the circle is:

`4(9)/(28)\text{ yards}`
