Question

Find the area and the circumstances of a circle with diameter 6 yd. use the value 3.14 for n, and do not round your answers. Be sure to include the correct unit in your answers.

Answer 1

SOLUTION

It is given that the diametr of the circle is 6 yd.

Since radius is half of diameter, It follows that the radius is 3 yd.

Therefore the area of the circle is:

$\begin{gathered} A=\pi r^2=3.12\times3^2 \\ A=28.26 \end{gathered}$

Therefore the area of the circle is 28.26 square yard.

The circumference of the circle is:

$\begin{gathered} C=2\pi r=2\times3.14\times3 \\ C=18.84 \end{gathered}$

Therefore the circumference of the circle is 18.84 yd.
