Answer: y=-9/3+27/3
Step-by-step explanation:
D. Umm explanation you’re not asking for who but the number of students.
You use the cricle fourmla (πr sqaure). and you will get 7.065
Y=mx+c
y=7/18x+c
now we will find the value of c
20=7/18*4+c
20=28/18+c
20=14/9+c
20-14/9=c
180-14/9=c
18.4=c
so the equation is y=7/18x+18.4
