A flying disc has a 5 ⅖ inch radius. What is its approximate circumference, rounded to the nearest inch?
Ivenika [448]
<h2>Circumference of flying disc is 34 inches</h2><h3><u>Solution:</u></h3>

Given that,

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

To find: circumference

<h3><u>The circumference of circle is given as:</u></h3>

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

A dog is on a 20-foot leash in the backyard. Approximately how much area does the dog have to move around in the yard?
iragen [17]
With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256


Answer = 1256
