A solid aluminum sphere has a mass of 88g Use the density of aluminum to find radius of sphere?

Density = mass / volume. You have the density of aluminum and the mass of the aluminum sphere. The volume of a sphere is 4/3*Pi*r^3. Therefore volume = 4/3*Pi*r^3 = mass / density. Solve for r, which is the radius of the sphere.

Density = mass/ volume
Volume sphere = 4/3 pi r3
mass sphere = 88 g (two significant figures)
Volume = mass / density
4/3 pi r3 = 88/2.7
= 32.59 cm3
r3 = 32.59 x 3/4/pi
= 7.78
r = 1.15
= 1.2 cm (two significant figures)

Definition of volume of a regular solid?
There isn't a single formula for solids of different shapes. For a right solid with a rectangular base, volume is base area x height. Similarly for cylinder with a circular base, volume = base area x height (base area in this case is Pi x radius2). For a sphere, volume = 4/3 x Pi x radius3.
Why should use an inoculating needle when making smears from a solid media?
You should use an inoculating needle when making smears from solid media because of the solid's density. The smaller areas are denser, so it is easier to retrieve these specimens using an inoculating needle.
What is a trait of a substance by itself?
Substances have many different traits, which include such things as phase (solid, liquid, or gas), density, hardness, color, reactivity, flexibility, scarcity or abundance, toxicity, etc.
What is the density of silver at room temperature?
The density of silver at room temperature is 10,49 g/cm3. The relative density is the same. Pure silver is very hard to find on Earth. Generally, silver found has a density which ranges from 10 to 12 gram per cubic centimeter based on the amount of impurity.
What is special about water and density?
Density rho = mass / Volume. Water has a density of 1,000 kg/m3 = 1,000 g/L = 1.000 kg/dm3 = 1.000 kg/L = 1.000 g/cm3 = 1.000 g/mL at the temperatur of 3.98 degrees Celsius. Temperature in degrees Celsius and the density of water: 1 999,902 999,943 999,964 999,975 999,966 999,947 999,90 You see the highest number at 4 degrees Celsius.
How do you find the radius of a sphere based on the weight in pounds?
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
A solid rectangular block of metal 49cm by 44cm by 18cm is melted and formed into a solid sphere find the radius ofthe sphere?
54.7
How many balls of radius 4 cm can be made from a solid sphere of lead of radius 8 cm?
16
How do you derive the moment of inertia of solid sphere?
mass moment of inertia for a solid sphere: I = (2 /5) * mass * radius2 (mass in kg, radius in metres)
What is a steradian?
A steradian is the solid angle subtended at the centre of a sphere by radius r by a portion of the surface of the sphere which has area r2.
What part of the earth is a solid metallic sphere about 1216 kilometers in radius?
inner core
What part of earth is a solid metallic sphere about 1216 kilometers in radius?

Why Does an aluminum can float on water but an aluminum pole does not?
Because the overall density of a can is less than the density of water, a solid aluminium pole has a density greater than water
What is the radius of a solid aluminum sphere that has a mass of 87g in inches?
Mass = 87 grams and density of aluminium = 2.7g/cm3 So volume of spere = Mass/Density = 87/2.7 = 32.22... cm3 Then V = 4/3*pi*r3 = 32.22.. cm3 r3 = 32.22...*3/(4*pi) = 7.6925 so that r = 1.97 cm = 0.78 inches.
How do you determine density of sphere with Vernier caliper?
Measure the diameter and from that calculate the volume, then determine the mass of the sphere on a weighing device. Then it's just density = mass/volume ========================== It again depends on the sphere whether its hollow or its a solid sphere
Aluminum sphere float in water?
If it was solid, no it would not float in water since it would displace less water than its weight. In other words, the density of aluminium is higher than the density of water, and denser objects will sink. If it were a hollow sphere and displaced more weight in water than its own weight, it could float - but that would not be by virtue of the density of aluminum, it would be because it was hollow.
What is the name of the regular solid whose surface area is 4 times the radius squared?
