I think the answer above is correct
A is the true statement because the variable g us counted as 1 so then we subtract 6 from 1 =5g
y = 316
because 98 times 3 equals 294. Then add 22 and your whole answer is
y = 316.
You can calculate the arc lenght by using this formula:
arc length = 2π*r*(A/360) , where A=angle of the arc.
So for you it would be:
arc length = 2π*4*(72/360) = 5.03
I hope that helped.
