A truck has a cylindrical tank 9 m long for transporting milk. The diameter of the tank is 2.8 m.
How much milk can it hold? (Use 3.14 for π.)
Volume = π r^2 h
= π(1.4)^2 (9)
= appr 55.418 m^3
= appr 554000 L, rounded to the nearest thousand litres.
Ok so you have to divide the diameter by 2 which is 1.4. Now we mutiply 3.14*1.4*2*9=79.128 2*3.14*1.4*1.4=3.5168 79.128+3.5168=82.6448 We can reduce this to get 82.6. What I did was just to see if the 4 was higher than five and it wasn't so we just have 6. I hohe this helps. :)
Unless you know what you are doing, it doesn't help to answer questions for other students incorrectly.
your line of :
3.14*1.4*2*9=79.128 2*3.14*1.4*1.4=3.5168 79.128+3.5168=82.6448
is total mathematical gibberish.
To find the volume of a cylindrical tank, we need to use the formula:
Volume = π * r² * h
Where:
- π is a mathematical constant approximately equal to 3.14.
- r is the radius of the cylindrical tank.
- h is the height of the cylindrical tank.
First, we need to find the radius of the tank. We know the diameter (2.8 m), and the radius is half of the diameter. So:
Radius = diameter / 2 = 2.8 m / 2 = 1.4 m
Now, we can find the volume using the formula:
Volume = π * (1.4 m)² * 9 m
Volume = 3.14 * 1.4 m * 1.4 m * 9 m
Simplifying this equation will give us the answer.
Note: Make sure to perform the calculations carefully to get an accurate answer.
