I think the correct answer is C. Since a=πr², in order to get the area to become 1/4 of what it was previously, the radius needs to be cut in half to make the divide that side by 4.  a=π(r/2)²=πr²/4 and will therefore multiply the area by 1/4.

A paper air plane looking polygon with sides of 5 5 and 8 what is the area
VARVARA [1.3K]
If it has 3 sides then it's a triangle. 
Using the formula A= \sqrt{s(s-a)(s-b)(s-c)} 
where s= \frac{a+b+c}{2}
and  a=5 b=5 c=8

∴s= \frac{5+5+8}{2} =9
  area= \sqrt{9(9-5)(9-5)(9-8)}
  area= \sqrt{144} = 12units^{2}
