(a)

\

An archer using a target with \"\" radius shoots arrows at \"\", \"\" and \"\".

\

For the point \"\":

\

Locate the terminal side of a \"\" angle with the polar axis as its initial side.

\

Plot a point \"\" units from pole along the terminal side of the angle.

\

 

\

For the point \"\":

\

Locate the terminal side of a \"\"angle with the polar axis as its initial side.

\

Plot a point \"\" units from pole along the terminal side of the angle.

\

 

\

For the point \"\":

\

Locate the terminal side of a \"\" angle with the polar axis as its initial side.

\

Plot a point \"\" units from pole along the terminal side of the angle.

\

If the 60 cm ring subdivided into 10 evenly spaced concentric circles, then

\

each circle is separated by 6 cm distance.

\

Concentric circles scored values from 1 to 10 points from the outer circle to center.

\

Therefore score values are as below table.

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

\"\"\"\"
\

The shot at \"\" earned \"\" point, the shot at \"\" earned \"\" points and

\

the shot at \"\" earned \"\" points.

\

So the archer earned total of \"\" points.
