How many times will the wheel of a car rotate in a journey of 88 km given that the diameter of of wheel is 56 cm?
Well, isn't that a lovely question! To find out how many times the wheel will rotate, we first need to calculate the circumference of the wheel using the formula 2 x π x radius. Then we can divide the total distance of 88 km by the circumference of the wheel to find our answer. Just remember to breathe, take your time, and enjoy the journey of learning something new today.
How many times is the circumference bigger than the diameter of a circle?
The circumference of a circle is 3.14159… times, or pi times bigger than its diameter.

How many times will the radius fit on the circles circumference?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. To determine how many times the radius fits into the circumference, you divide the circumference by the radius: ( \frac{C}{r} = \frac{2\pi r}{r} = 2\pi ). Therefore, the radius fits approximately 6.28 times around the circumference of the circle.
How many revolutions are made by a wheel 40cm in diameter in travelling 352m?
Diameter = 40 cm implies circumference = 40*pi = 125.7 cm So, in travelling 352 metres = 35200 cm, the wheel will rotate 35200/125.7 = 280.1 times (approx).
