Answer:

Step-by-step explanation:

Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.

Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.

Hence the answer is Graph A.

Answer:

114 cm²

Step-by-step explanation:

Area of shaded region

= area of circle -area of square

$\boxed{area \: of \: circle = \pi {r}^{2} }$

Given that radius= 10cm, r= 10cm.

$\boxed{area \: of \: square = side \: \times side}$

Let the length of a side of the square be x cm.

Applying Pythagoras Theorem,

10² +10²= x²

100 +100= x²

x²= 200

$x = \sqrt{200}$

Area of square

= x²

= 200cm²

Area of shaded region

= 3.14(10²) -200

= 3.14(100) -200

= 314 -200

= 114 cm²
