Answer:

Formula for arc length =

arc length = r θ where θ is in radians

So we have

2pi = 5 θ solve for θ and we have that

θ = [ 2 pi ] / 5

The area of the sector =

(1/2) r^2 θ = (1/2)(5^2) (2pi) / 5 = 5 pi in^2 ≈ 15.7 in ^2

The rectangular shape has more area = (5 * 4) = 20 in ^2

Explanation:

I don't think this will help but hope it does
