<u><em>The </em></u><u><em>number of trains</em></u><u><em> that arrived Dubai metro station on time is; 272 trains. </em></u>
<u><em /></u>
- We are told that 320 trains arrived the Dubai metro station in a week.
- Now, we are told that 5% got there early and 15% got there late.
This means, the percentage that got there on time is;
100% - % of trains that got there late.
- Therefore, percentage of trains that got there on time is;
100% - 15% = 85%
- Since 85% of the trains got there on time, then number of trains that got there on time is;
85% × 320 = 272
- Therefore, we can conclude that 272 trains arrived on time.

Answer:
A≈28.26 in^2
Step-by-step explanation:
We know the diameter is 6
We can find the radius
r = d/2
r =6/2 =3 inches
The area of a circle is given by
A = pi *r^2
A = pi*3^2
A = pi*9
We will use 3.14 to approximate pi
A ≅(3.14) *9
A≈28.26 in^2
