Half  the length of the curve which separates the 2 halves = 1/2 circumference of a circle with diameter 6 mm.  = 1/2 * pi * d = 3pi mm

So the length of the line = 6pi =  18.85 mm to nearest hundredth. answer

The area of shaded region = 1/2 area of the circle = 1/2 pi r^2

= 1/2 * pi * 6^2

=  56.55 mm^2  to nearest hundredth  answer

30 points.. Please Help! I don't understand what to do with this question...a bit confused.
Romashka-Z-Leto [24]
  Eh, here's my best try for a table:

                       <u>Like tv</u>          <u> don't like tv</u>       <u>total</u>
<u>Like reading:</u>     70                     10                 80
 <u>Don't like read</u>. <u>20</u>                     <u>30</u>               <u>50 </u> 
      <u>total </u>              90                    40               130

The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.

The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]

Hope this somehow helped you :)
