Y=(1/2)x cause the constant variation is 1/2
Ok
A=bh
plug in
126 square meters=6b
126/6 6/6
21=b
base length=21meters
Solution: It would be quadrupled because radius controls to axis (height & width) meaning if you double two (2 x 2) you get four (4).
a) 2/5(n)=6 n=15
b) 4/7(x)=16/3 x=28/3 x=9.33333 x=9 1/3
any option for b works
i hope this is right and helps
