Question

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

Answer 1

Circumference of flying disc is 34 inches

Solution:

Given that,

$Radius = 5\frac{2}{5}\ inches = \frac{27}{5}\ inches$

To find: circumference

The circumference of circle is given as:

$C = 2 \pi r$

Where, r is the radius of disc

Therefore,

$C = 2 \times 3.14 \times \frac{27}{5}\\\\C = 6.28 \times 5.4\\\\C = 33.912$

$C \approx 34$

Thus the circumference of flying disc is 34 inches
