Question

The co-relation between area of a circle and a rectangle :( obtained by cutting the circle to unit triangles of equal size and placing them side by side to form a rectangle).

Answer 1

The co-relation between area of a circle and a rectangle

Step-by-step explanation:

Lets cut 12 triangle out of circle with 30° angle at center

now cut one triangle into two Equal parts

place 11 triangle side by side and half piece of last triangle on both sides

so we will get a rectangle shape

with height =  radius

and Length would be  = ( half of Circumference) = πr

hence area of rectangle = πr * r = πr²  = area of circle

only issue is that length of rectangle is not a straight line

so as the number of triangle increases  , straightness in line increases
