Pi*r^2=70*pi
So r=sqrt{70}
Hypotenuse of triangle will be=sqrt{70+70}
Sonperimeter will be 2*sqrt{70}+sqrt{140}
B should be the correct choice

Pi r² = 70 pi

=>r² = 70

Two sides of right triangle is root(70)

2(root(70)) +hypotenuse

By theorem hyp = root (root(70)² + root(70)²)

=root(140)

So answer B
