Answer:
36 π
Step-by-step explanation:
Since the diameter is 6, the radius is 3. The formula for surface area of a sphere is 4 π r², so when you plug in 3 for r(radius), you get 36 π
Do 12 divided by 15 and you will get the decimal for any fraction. 12/15 = .8
The answer to question 3 is 1 person orders chicken and the other 5 had steak dinner.
the way you work this out is you half 6 which is three and then do 3x14 and 3x17
3x14=42
3x17=51
42+51=93
this is too less so you have to do less of the cheaper meal (14) and more of the dearer one (17) so I went to 1x14 and 5x17
1x14=14
5x17=85
14+85=99
add these together and it makes 99
the answer to question 14 is 5 adults and 3 students
to do this you do exactly the same as how you do question 3
