-3, -4 ,-5, -6, -7 ,-8, ,5 ,6 ,4 ,3, 2

Answer 2

Determine the area of circle

Step-by-step explanation:

Cut the circle in 16 Equal parts

Arrange them as shown in figure like a rectangle

2 ( length of rectangle )  = Perimeter of circle = 2πr

=> 2 ( length of rectangle )  =  2πr

=>  length of rectangle = πr

Breadth = r  = radius of circle

Area of rectangle = length x breadth

=  πr *  r

=  πr²

Hence area of circle  =  πr²
