Question

the radius of a circular field is 24.5 M find the distance run by a boy in making four the the complete rounds

Answer 1

______________________________

GIVEN :

=> THERE IS A FIELD WHICH IS CIRCULAR

______________________________

RADIUS OF THAT FIELD :

=> 24.5 M

______________________________

TO FIND :

=> THE DISTANCE RUN BY A BOY IN 4 ROUNDS

______________________________

STEP 1 :

=> FIND THE CIRCUMFERENCE OF THAT CIRCULAR FIELD

_______________________________

FORMULA FOR :

=> CIRCUMFERENCE OF ANY CIRCLE :

=> 2 * π * R

_______________________________

PUT THE VALUES :

=> 2 * 22 / 7 * 24.5

=> 44 / 7 * 24.5

=> 44 * 3.5

=> 154 M

______________________________

WE GOT THE CIRCUMFERENCE OF THAT FIELD :

=> NOW THE BOY HAD COMPLETED 4 ROUNDS OF THE FIELD :

=> MEANS HE HAD COMPLETED THE DISTANCE WHICH IS 4 TIMES THE CIRCUMFERENCE OF THAT FIELD :

______________________________

TO FIND THE DISTANCE :

=> MULTIPLY THE CIRCUMFERENCE BY 4

=> 4 * 154 M

=> 616 M

______________________________

AND THE ANS IS :

=> BOY HAD RUN 616 M DISTANCE
