Question

A flying disc has a 5 ⅖ inch radius. What is its approximate circumference, rounded to the nearest inch?

Answer 1

34 inches

Explanation:

we know that

The circumference of a circle is equal to

`C=2\pi r`

we have

`r=5(2)/(5)\ in= 5+(2)/(5)=(5*5+2)/(5)=(27)/(5)\ in`

assume

`\pi =3.14`

substitute

`C=2(3.14)(27)/(5)=34\ in`
