Question

Teena is cycling at the speed of 10 kilometre per hour how long will it take to make a round of a circular field of radius 50 cm take for equal to 3.14​

Answer 1

Step-by-step explanation:

The circumference of the circle is given by 2pie x r

= 2 X 3.14 X 0.5 m

= 3.14 m

Teena's speed = 10 X 1000/ 3600 m/s

= 2.7 m/s

therefore time required = distance/velocity

= 3.14/ 2.7

= 1.16 seconds

hope you understand......
