A cylinder container has a radius 5 cm and height 10 cm filled with water.
If a filled container weight is 2 kg.
What is the weight of the empty container ?
volume = πr^2 h
= π(25)(10) cm^3
= appr 785.4 cm^3
by the beauty of the metric system, that would be .7854 kg of water
so the empty container weighs
2 - .7854 or aprr 1.21 kg
Well, it sounds like you really need to lighten up with this question! But I'm here to help, so let's get to it.
First, let's calculate the volume of the cylinder container. The formula for the volume of a cylinder is π * r^2 * h, where π is approximately 3.14, r is the radius, and h is the height. Plugging in the values, we get:
π * 5^2 * 10 = 250π cm^3
Now, let's convert the volume to liters because it's easier to work with. Since 1 liter is equal to 1000 cm^3, we divide the volume by 1000:
250π cm^3 ÷ 1000 = (250π/1000) L = (π/4) L ≈ 0.7854 L
Next, we need to find the weight of water in the container. Since 1 liter of water weighs 1 kg, the weight of the water in the container is 0.7854 kg.
Finally, we subtract the weight of the water from the weight of the filled container to find the weight of the empty container:
2 kg - 0.7854 kg ≈ 1.2146 kg
So, the weight of the empty container is approximately 1.2146 kg.
But remember, numbers can be heavy! So take these calculations with a grain of salt... or maybe a grain of sugar if you prefer a sweeter approach!
To find the weight of the empty container, we need to subtract the weight of the water from the weight of the filled container.
The weight of the water can be calculated using the formula:
Weight = Volume x Density
The density of water is approximately 1 kg/cm³.
To find the volume of the water, we can use the formula for the volume of a cylinder:
Volume = π x (Radius)² x Height
Given:
Radius (r) = 5 cm
Height (h) = 10 cm
First, let's calculate the volume:
Volume = π x (5 cm)² x 10 cm
= 250π cm³
Now, we can calculate the weight of the water:
Weight of water = 250π cm³ x 1 kg/cm³
= 250π kg
Given that the weight of the filled container is 2 kg, we can subtract the weight of the water from the weight of the filled container to find the weight of the empty container:
Weight of empty container = Weight of filled container - Weight of water
= 2 kg - (250π kg)
≈ 2 kg - 785 kg
≈ -783 kg
Therefore, the weight of the empty container is approximately -783 kg.
To determine the weight of the empty container, we need to subtract the weight of the water from the weight of the filled container.
First, let's calculate the weight of the water:
The formula to calculate the weight of an object is weight = mass * gravity, where gravity is approximately 9.8 m/s^2.
Given that the weight of the filled container is 2 kg, we can assume that the mass of the water is equal to 2 kg. So, the weight of the water is 2 kg * 9.8 m/s^2 = 19.6 N (newtons).
Next, since the container is cylindrical, we can use the formula for the volume of a cylinder to find the volume of the cylinder. The formula to calculate the volume of a cylinder is volume = π * r^2 * h, where π is a mathematical constant approximated as 3.14159, r is the radius, and h is the height.
Substituting the given values, we have volume = 3.14159 * (5 cm)^2 * 10 cm = 785.398 cm^3.
Now, we need to consider the density of water. The density of water is approximately 1 g/cm^3 or 1000 kg/m^3. Since the volume is in cm^3, we can convert the density to g/cm^3.
Since 1 g/cm^3 = 1000 kg/m^3, we have 1000 kg/m^3 * (1 cm^3 / 1000 cm^3) = 1 kg/cm^3.
Multiplying the volume of the water by the density, we get 785.398 cm^3 * 1 kg/cm^3 = 785.398 kg.
Therefore, the weight of the empty container can be calculated by subtracting the weight of the water from the weight of the filled container:
Weight of empty container = Weight of filled container - Weight of water
Weight of empty container = 2 kg - 785.398 kg = -783.398 kg.
However, the weight of the empty container cannot be negative. Therefore, it is likely that some information or calculations in the given question are incorrect.
