HIIIIIII BRAINLY USERS ☺️☺️

How Are You????

I HAVE A BRAINLIEST QUESTION FOR U MATE!!!!

MY QUESTION IS THIS :-






THE AREA OF A CIRCLE IS EQUAL TO THE AREA OF RECTANGLE WITH SIDES 112 m AND 88 m RESPECTIVELY. SO,,,,,
FIND THE CIRCUMFERENCE OF THE CIRCLE.

Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

Length of the rectangle = 112 m

Breadth of the rectangle = 88 m


• Area of the rectangle

= length × breadth

= 112 m × 88 m

= 9856 m²


• Now, area of circle = area is rectangle

=> Area of the circle = 9856 m²


• But, area of any circle = πr², where π (pi) is taken as 22/7 and r is the radius of the circle.

Then,

πr² = 9856

=> 22/7 × r² = 9856

=> r² = 9856 × 7/22

=> r² = 68992/22

=> r² = 3136

=> r = √3136

=> r = √(56 × 56)

=> r = 56.


• So, the Radius of the circle = 56 m


• Now, circumference of any circle = 2πr


So, circumference of the given circle

= 2πr

= 2 × 22/7 × 56

= 2 × 22 × 56/7

= 44 × 8

= 352 m
