Diameter be d 
Radius be r
- πr²=6767
- r²=6767/π
- r²=2155
- r=46.4cm
Diameter=2r=46.4(2)=92.8cm

The probability is .034375 or 11/320
Step-by-step explanation:
the probability of a senior being chose first is 22 (seniors) divided my total number of students (80) is .275 percent. 
multiplied by the probability of a sophomore being chosen 10/80 which equals .125. 
multiply those together and you get your probability. 0.034375 or 11/320
