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.
The volume of a sphere V = ⁴⁄₃πr³ would be near enough.
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.
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).
Volume of the sphere: 4/3*pi*2^3 = 33.5 cubic meters to one decimal place
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.
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.
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
the volume of a sphere is 4/3 (pi) r^3, so if r= 9 then volume would be approximately 3053.63m
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.
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.
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.
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.
