Question

how many revolutions will a wheel 2.8 meters in diameter make in traveling a distance of 880 metres?

Answer 1

Answer:

plz mark as brainliest

Step-by-step explanation:

Well first you'd need to calculate the circumference of the wheel. Using 2pi r.

Where r is the radius, which is half of the diameter.

All must be in metres. So half the diameter is 0.14m. So 2 x pi x 0. 14 = 0.879m. This is the measurement all the way round the wheel.

So this would tell you how far it would go in one revolution. Now you only need to divide the distance by the circumference of the wheel.

352m/0.879m =400.45 revolutions.

Hope this helps

Answer 2

Answer:

The total number of revolutions will be 100.

Step-by-step explanation:

It is given to us that :

Distance = 880m

Wheel diameter, D = 2.8m

So we require the circumference of the wheel at first,

Therefore, circumference of the wheel, C = $\pi D$

where $\pi$ = $\frac{22}{7}$ and D = diameter of the wheel = 2.8m

So, circumference = $\frac{22}{7}$ x 2.8 =  $\frac{44}{5\\}$

Now, we know that :

Distance travelled   = Number of revolutions x Circumference

or, 880 = Number of revolutions x $\frac{44}{5\\}$

or, Number of revolutions = $\frac{880 * 5}{5}$ = 100

Therefore, the total number of revolutions will be 100.
