The volume of a sphere of radius r is given by
For your given conditions, the volume of 1/2 a sphere becomes
Seems to match your 2nd choice:
... 1 over 24 over 322 over 7(83)
STEP 1:
Add the number of total students
= 27+25+23
=75
STEP 2:
Find the percentage that 18 out of 75 students is.
18/75=x/100
cross multiply
(18*100)=(75*x)
1800=75x
divide both sides by 75
24%=x
Check:
75 * 24%= 18
Hope this helps! :) Good luck!
