<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 =
<h3>Then, </h3>
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
<h3>Thus, </h3>

<h3>Therefore, total of 55,000 revolutions are made by the wheel.</h3>
Answer:
Step-by-step explanation:
The term dilate means that the new cone is wider, broader, or bigger than the cone in the given. I would assume that the given scale is 1:3. This means that the dimensions of the second one is 3 times than those of the first. We cube 3 and multiply the answer with the given volume of the original cone in order to solve for the volume of the second cone. That is,
volume of second cone = (1350 m³)(3³)
= 36,450 cm³
PEMDAS
-3(-2)^2-12(-2)+3
-3(4)-12(-2)+3
-12-12(-2)+3
-12+24+3
12+3
=15
It would take 20 hours since 8,000 times 5 is 40,000 so 4 times 5 is 20.
