How many revolutions must be made by a wheel of diameter 2.8m in order to cover a distance of 484km?

arlik [135]

<h2>Answer :</h2>

A wheel is a circle.

Given diameter of wheel = 2.8 m

Then radius of the wheel = 2.8/2 = 1.4 m

Now we know that , circumference of circle = $2\pi r$

Circumference of wheel = 2 × 22/7 × 1.4

Circumference of wheel = 8.8 m

<u>From the above we can conclude that ;</u>

1 revolution = 8.8 m

x revolution = 484 km = 484000 m

$x = \frac{1}{8.8} \times 484000 \\ \\ x = 55000$

<h3>Therefore, total of 55,000 revolutions are made by the wheel.</h3>

Apply the communitive property to 13x7x21 to rearrange the terms and still get the same solution

Snezhnost [94]

The commutative porperty states that numbers can be swapped over , they can change their place in the equation and the result will still be the same.
In our case 13 x 7 x 21, the commutative property means that the numbers can be rearranged
13x7x21=13x21x7=7x21x13=7x13x21
