How many students tired out for the volleyball team is this a statistical or no
vodomira [7]

That question is not a statistical question since there will be only one answer. If it were to be statistical it would have multiple answers an example of that type of question would be, Why did you decide to try out for the volleyball team? This is statistical because some could say they joined for fun, credits, to do something active, etc.. there would be multiple answers. Your question, How many students tried out for the volleyball team isn't statistical since it will have one answer such as, 26 students, 15 student, 2 students, etc...

Hope this helped!

I really need help please!

As we know that angle of semi circle is 180°.

Here,

FLG = 40°

GLH = ?

HLJ = 60°

FLG + GLH + HLG = 180°

40° + GLH + 60° = 180°

GLH + 100° = 180°

GLH = 180° - 100°

GLH = 80°

Now,

FLH = 40° + 80° = 120°

\sf \: Length \:  of  \: an \:  arc  \: of \:  GHF =   \dfrac{ \theta}{360}  \times 2 \pi \: r

=  \dfrac {120}{360}  \times 2 \times  \dfrac{22}{7}  \times r

=  \frac{1}{3}  \times  \frac{44}{7}  \times r

=  \frac{44}{21}  \times r

= 2.09r
