Chapter 11, Problem 33SGR

To determine

To calculate the circumference.

Answer to Problem 33SGR

44 yd.

Explanation of Solution

Given Information: Diameter = 14 yd.

Formula Used:Circumference of circle = $2\pi \times r$ , $\pi =\frac{22}{7}$ , $radius=\frac{diameter}{2}$ .

Calculation:

Diameter = d, Radius = r.

Now, diameter is of 14 yd.

So, $radius=\frac{diameter}{2}$

  $radius=\frac{14}{2}yd$

  $radius=7yd$

Circumference of circle = $2\pi \times r$

Circumference of circle = $2\pi \times 7yd$

Circumference of circle = $14\pi yd$

Now, $\pi =\frac{22}{7}$

Circumference of circle = $14\times \frac{22}{7}yd$

Circumference of circle = 44 yd.
