Question

Расчитайте объём полости внутри медного шара имеющего массу-890г. при объёме-150 см.

Answer 1

V2 меди = 890/8900 = 0,1 дм^3 = 100 см^3.

V3 полости = 150 - 100 = 50 см^3.

Ответ: 50 см^3.

Answer 2

Calculation of the Volume of a Copper Sphere

To calculate the volume of a copper sphere, we need to know its mass and the volume it occupies. In this case, we have the following information:

- Mass of the copper sphere: 890 grams - Volume of the copper sphere: 150 cubic centimeters

To calculate the volume of the cavity inside the copper sphere, we can subtract the volume of the copper sphere from the total volume of the sphere.

Let's calculate the volume of the copper sphere first:

Volume of the copper sphere = 150 cubic centimeters.

Now, we need to calculate the radius of the copper sphere. We can use the formula for the volume of a sphere to find the radius:

Volume of a sphere = (4/3) * π * r^3

Since we know the volume of the copper sphere and the value of π (pi is approximately 3.14159), we can rearrange the formula to solve for the radius:

r = (3 * (Volume of the copper sphere) / (4 * π))^(1/3)

Substituting the values, we get:

r = (3 * 150 / (4 * 3.14159))^(1/3) ≈ 3.861 centimeters

Now that we have the radius, we can calculate the volume of the cavity inside the copper sphere. The volume of a sphere is given by the formula:

Volume of a sphere = (4/3) * π * r^3

Substituting the radius, we get:

Volume of the cavity = (4/3) * π * (3.861)^3 ≈ 238.48 cubic centimeters

Therefore, the volume of the cavity inside the copper sphere is approximately 238.48 cubic centimeters.
