ATQ:-
Perimeter of rectangle=Circumference of circle
So let the radius of circle be r cm
Length of rectangle=40 cm
Breadth of rectangle=26 cm
Now:-
Therefore,the radius of the circle is 21 cm
Perimeter of rectangle=Circumference of circle
So let the radius of circle be r cm
Length of rectangle=40 cm
Breadth of rectangle=26 cm

Answer:
PERIMETER OF RECTANGLE =CIRCUMFERENCE OF CIRCLE
SO LET THE RADIUS OF CIRCLE BE RCM
LENGTH OF RECTANGLE 40CM
BREADTH OF RECTANGLE =26CM
=2(L+B)=2R*R=2(40 +26)=2*22/7*R
=2*66=44/7R
=2*66*7/44=R
=R=21
THEREFORE THE RADIUS OF THE CIRCLE IS 21 CM.
