Answer 7

The arc length of a circle is given by the following formula:
\[l=\frac{ \theta }{ 360 }*2*\Pi*r\]
The area of a sector is then given by :
\[A=\frac{ \theta }{ 360 }*\Pi*r ^{2}\]

Next if we try to make ratio by doing l=A, we can firstly cancel all common terms between these 2 formulas. The common terms are theta,360 and pi.
Then the formulas of length as to area become
2r : r^2, one r is common between the two the ratio of them finally becomes
2 : r

Thanks @Hoslos I already finished the assignment on my own! :D
