Question

Tina is cycling at the speed of 10 km/h how long will she take to make a round of a circular field of radius5 m square

Answer 1

Answer:

Step-by-step explanation:

First we need to convert metre into km,

⇒ 5 ÷ 1000 = 0.005km

Now we need to find the circumference of the circle,

⇒ Circumference = 2πr

⇒ Circumference = 2 × 3.142 × 0.005

⇒ Circumference = 0.031m

The time Tina will take will be,

⇒ Time = Distance ÷ Speed

⇒ Time = 0.031 ÷ 10

⇒ Time = 0.0031 hours

And that's your answer! Please mark as brainliest :)
