Density is mass divided by Volume The volume of a cylinder is pi*r^2*h
So the volume of your cylinder is pi*16*15. Using 3.14 for pi that means the volume is = 753.6 cm^3 Dividing 7 by 753.6 = 0.009288

The moment of inertia of a solid cylinder is?
the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.
Volume of cylindrical solid?
πr2h or the radius squared multiplied by pi multiplied by the vertical height of the cylinder.
A solid cylinder 1m in diameter and 0.8m high is of uniform relative density 0.85 Calculate the periodic time of small oscillations when the cylinder floats with its axis vertical in sill water?
A solid cylinder 1m in diameter and 0.8m high is of uniform relative density 0.85. Calculate the periodic time of small oscillations when cylinder floats with its axis vertical in still water
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)]
How do you calculate the area of a cylinder?
Pi times Radius times Radius times Height.Area of cylinder depends on which side you want.The top and bottom parts = Pi times Radius times Radius. (∩r2)The round part = Pi times Diameter (or 2 * Radius) times Height (∩Dh)Volume = Pi times Radius times Radius times Height (∩r2h)Note: ∩=PiThe area is the outer surface.The surface of a right truncated circular cylinder is calculated as follows:PI * r2 * hwhere PI is the irrational: 3.15158...r is the radiush is the heightIf it is a solid (or a closed shell) then you have to add the ends:twice the area of the circular cross section: PI * r2The volume of a cylinder is equal to Pi times the square of the radius times the height of the cylinder. Pi*r2*h. Pi*r2 is the area of the base of a cylinder. The surface area of a cylinder is 2*Pi*r2+Pi*2r*h. 2*Pi*r2 is the area of the base of the cylinder times two to account for both bases. Pi*2r*h is the circumference of the base times the height of the cylinder
How do you work out the density of a solid aluminium cylinder the radius is 38mm and the height is 16.7mm and the volume is 75758.88mm3?
You cannot. You have the volume but no information on the mass. And density = mass/volume (in the appropriate units of measurement).
How do you measure the mass of a solid with a graduated cylinder without the density?
You cannot measure the mass of a solid with a graduated cylinder.
What is the radius of gyration of a flywheel in the form of a uniform cylinder of radius 0.43m?
The radius of gyration of a uniform cylinder is half of its radius, so for a cylinder with a radius of 0.43m, the radius of gyration would be 0.43m/2 = 0.215m. It is the distance from the axis of rotation where the mass of the cylinder may be concentrated without changing its moment of inertia.
The moment of inertia of a solid cylinder is?
the moment of inertia of a solid cylinder about an axis passing through its COM and parallel to its length is mr2/2 where r is the radius.
What is the perimeter of a cylinder whose height is 4cm with a radius of 3.5cm?
Solid objects do not have perimeters.
Volume of cylindrical solid?
πr2h or the radius squared multiplied by pi multiplied by the vertical height of the cylinder.
The order of densities of the liquids and solids in the cylinder?
From highest to lowest density, the order would be: solid gold, liquid mercury, solid silver, liquid water, liquid oil, solid foam. Gold is the densest material, followed by mercury, silver, water, oil, and foam in decreasing order of density.
What is the radius of a solid cylinder of lead whose height is 3.0 cm and has a weight of 2.5 lbs?
The density of lead is 11.34 g/cm^3. This object weights 2.5 lbs., or 1133.98 g. Using these two facts, the volume of this cylinder is approximately 100 ml. Since the volume of a cylinder is equal to pi*r^2*h, simple algebra will solve this problem. The radius of the cylinder is approximately 3.26 cm, or 3.3 cm using significant figures.
Will density of a liquid increase if parts of the solid sticks out of the water?
No, the density of the liquid will not change based on whether parts of the solid stick out of the water. Density is solely determined by the mass and volume of the liquid present, regardless of the shape of the solid object in the liquid.
Formula for volume of a solid cylinder?
area = pi*r2*h where pi is the irrational constatnt approx equal to 3.1416, r is the radius and h the height of the cylinder.
A solid cylinder 1m in diameter and 0.8m high is of uniform relative density 0.85 Calculate the periodic time of small oscillations when the cylinder floats with its axis vertical in sill water?
A solid cylinder 1m in diameter and 0.8m high is of uniform relative density 0.85. Calculate the periodic time of small oscillations when cylinder floats with its axis vertical in still water
When a sorlid is immersed in measuring cylinder the water level rises by 30ml if the solid weights 60 find its density?
The volume of the solid can be calculated as 30 ml since it displaced that much water. Using the formula Density = Mass/Volume, the density of the solid is 60g / 30ml = 2 g/ml.
