1. Measure the radius of the sphere.
2. Cube the radius.
This is basically multiplying the radius by itself three times, (RxRxR).
3. Multiply the answer by pi. (If this is a school homework assignment, and the instructions say "exact value", just write the greek letter pi. Otherwise, use the decimal equivalent, 3.14159.)
4. Multiply the previous answer by four thirds.
There are several ways to do this: * Option 1: on your calculator, enter in the improper fraction, four thirds, then multiply it with the answer from the previous step. * Option 2: If your calculator does not allow you to input fractions, multiply the answer to the previous step by four, then divide it by three. * If you have simply written the greek letter pi, instead of multiplying by 3.14 or something similar, then multiply only the coefficient of pi by 4. Then put the whole thing in the numerator of a fraction, with 3 as the denominator. Take to lowest terms.

What unit would be measure the mass of an orange?
The volume of a sphere V = ⁴⁄₃πr³ would be near enough.
How you would measure the density of a metal bolt?
To measure the density of a metal bolt, you would first weigh the bolt using a scale. Then, you would measure the volume of the bolt, for example by using a water displacement method. Finally, you would calculate the density by dividing the mass of the bolt by its volume.
What unit of measure would be appropriate for the volume of a sphere with a radius of 2 meters?
Volume of the sphere: 4/3*pi*2^3 = 33.5 cubic meters to one decimal place
What lab equipment would you need to measure the density of a piece of metal?
To measure the density of a piece of metal, you would need a balance to measure the mass of the metal piece, and a ruler or calipers to measure its dimensions (length, width, height). With this information, you can calculate the density by dividing the mass of the metal by its volume (calculated using its dimensions).
How much space will a 30Cm in a diameter metal ball occupy?
The volume of a sphere can be calculated using the formula V = (4/3)πr^3, where r is the radius of the sphere. Given that the diameter is 30 cm, the radius would be 15 cm. Plugging this into the formula, the volume of the sphere would be approximately 14,137.17 cubic centimeters.
What tools would a student need to find a density of a metal cube?
You would need a balance to measure its mass. You would need a ruler to measure the length of its sides. Then you would need to calculate volume. Then divide the mass by the volume to get density.
What is the volume of a sphere with a radius of 2.4 meters?
You can find the volume of a sphere by V = (4/3)*pi*r3 where r is the radius of the sphere. So in your case, the volume would be approximately 57.90583579 m3
What is the volume of a sphere of radius 9 meters?
the volume of a sphere is 4/3 (pi) r^3, so if r= 9 then volume would be approximately 3053.63m
What is the volume of a tennis ball in milliliter?
Measuring the volume of a baseball is a tough chemistry equation. To do so, you would have to measure the circumference to find the radius. Next, you would find the volume of a sphere. You would also have to know the density of water to complete the equation.
What is the volume of a sphere with a radius of 5 meters?
The volume would be (500pi)/3 since the formula for a sphere is (4r3pi)/3, when radius=r The volume is exactly 523.598776 cubic meters.
How large is a sphere that has a cubic volume of 020?
To find the diameter of the sphere, you must calculate the cube root of the volume. The cube root of 20 is approximately 2.71. Therefore, the diameter of the sphere is twice this value, which is approximately 5.42 units.
How would the densities of the sphere and cube have compared if the masses of the cube and sphere had been the same but the volume of the cube had been greater?
Density = Mass/Volume, whatever the shape. So, if the masses are the same, the density is greater when the volume id smaller. Thus the sphere, with the smaller volume has the greater density.
