Answer:
Step-by-step explanation:
To find the surface area of the cylinder you must apply the following proccedure:
- Calculate the surface area of the circles. They are equal, then you can multiply the surface area of a circle by 2:
Where r is the radius.
- Calculate the surface area of the rectangle:
Where l is the lenght and w is the width.
(The length is the circumference of the circle)
Then:
- Add the areas obtained.
The result is:
Answer:
The distance between Eddie's home and the school is 3000 m
Step-by-step explanation:
Consider the provided information.
His sister started walking at 8.00 am at an average speed of 50 m/min. Eddie started walking at 8.05 am at a speed of 60 m/min. Eddie caught up with his sister at mid-point between the school and his home.
Let the distance between school and home is x.
Let t is the time taken by Eddie sister to reach at mid-point between school and home.
Eddie caught up with his sister at mid-point between the school and his home.
That means his sister covers x/2 distance.
Speed of Eddie sister is 50 m/min.
.....(1)
Eddie started walking at 8.05 am at a speed of 60 m/min.
.....(1)
Equate both the equation as shown:
Hence, the distance between Eddie's home and the school is 3000 m
