<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:
b = 7.5
Step-by-step explanation:
- b × 2 = - 5 × 3
- 2b = - 15
- 2b ÷ - 2 = - 15 ÷ - 2
b = 7.5
