Answer:
12.1, 7.4
Step-by-step explanation:
First, we all know the formula its 2R however here we see the diameter to find R we have to divide: 12.1 divided by 2=6.05 but for me thats really useless because in the end you still have to multiply it by 2 so to find the circumference just find the diameter and add a pie beside it so the answer would be 12.1
for the others do the same thing. (pls give me brainliest or something)

Answer:
Number of student tickets were sold = 409
Step-by-step explanation:
Total number of tickets sold = 771
I.e Students ticket (S) + Non students ticket(N S) = 771
Total amount to be paid for tickets = $ 3037
Amount paid by students per tickets = $3
Amount paid by non-students per tickets = $5
So, according to question
S + NS = 771
3 S + 5 NS = 3037
Solve both equations
5 S + 5 NS = 771 × 5
3 S + 5 NS = 3037
so ,
(5 S + 5 NS) - (3 S + 5 NS ) = 3855 - 3037
Or, 2 S = 818
I.e S = = 409
Hence, The number of student tickets were sold = 409 Answer
