Question

Anyone can solve this please


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

Answer 1

$\bf\huge\color{red}{SOLUTION;}$

Diameter = 98 m
Perimeter = πD = π×98 = 308 m

speed of child = 14m/min

time = distance/speed = 308/14 = 22 minutes

Answer 2

circumference=πd
=22/7×98m
=308m
time taken=308/14
=22min
