Answer:

176cm²

Step-by-step explanation:

Side of square = 22cm

Perimeter of square = 88cm

Circumference of circle = perimeter of square

2π r = 88cm

2 x 22/7 x r = 88cm

44/7 x r = 88cm

r = 88 x 7/44

r = 14cm

Area of circle = π x r x r

= 22/7 x 14 x 14

= 44 x 4

= 176 cm²

Answer:

Perimeter of a square=circumference of circle

4×22=2πr

44=πr

r=14

Area of circle=πr2

22/7×14×14

disctirminant =b^2-4ac

disctirminant =(-4)^2-4.2.7

disctirminant = 16-56= -40

x=-b+square root of disctirminant ÷2a

x=4+2square root of (-10)/4

x=2+square root of (-10)/2

x'=4 -2 square root of (-10)/4

x'=2 -square root of (-10)/2

When the function goes 1 to the right, it goes 2 down. Therefore the direction of the function is
$\frac{-2}{ 1} = - \frac{2}{1}$
Hence, the function represented is
y = -2x
