Question

The diameter of a circular field is 98m. If a child walks at the rate of 14m per minute how long will it take to walk round the field once?

Answer 1

Answer:

Step-by-step explanation:

Answer 2

solution :
           Diameter of circular field = 98 m
therefore , Radius of circular field = 98/2 m =  49m

we know that Circumference of circular field = 2πr
                                                         = 2 *22/7*49
                                                         = 2*22*7
                                                          =44*7
                                 Circumference of Circular Field  =308m
Speed of Child = 14m / min
Therefore , time taken by the child to walk round the field =  circumference of circle/speed of child
                                     = 308 /14
                                   time taken   =22 minutes

Hope this helps You!!

Thank You!!!
