You cannot since you have no information regarding the shape. It could be a cylinder, a cone, a frustum, or one of many other possible shapes.
There isn't enough information to make a calculation. If the mass is known and the radius is known, we can see that a steel plate with the given mass and radius will be thinner than a plastic plate with the same mass and radius. And a uranium plate will be thinner than the steel one if it has the same mass and radius. Without the density of the material or a knowledge of what it is (so we can look up its density), we're dead in the water. We can't solve it.
you weigh the water
The smoke from a given volume of air is collected on a preweighed paper filter; density is mass/volume.
v= m/d v is volume m is mass d is density
To solve this you need to know the relationship that density = mass divided by volume We're given a length of a side of a cube as 2.5cm so to find the volume of the cube we need to cube it (length x bredth x height) volume = (2.5)3 = 15.625cm3 so if density = mass(136.95g)/volume(15.625cm3) density = 8.7648 g cm-3 in textbooks its given as (8.3- 8.7 gcm-3) as a typical density of brass.
The radius of a sphere is 1/2 of its height.
The radius of a cylinder given only the height could be anything you like.
The radius IS given, since height of hemisphere = radius of hemisphere!
That will depend on its height which has not been given but the volume of a cylinder is pi*radius squared*height.
Given what??? I'd probably measure it
Vol = 4/3*pi*r3 so given the volume, you can calculate the radius. Height of sphere = 2*radius.
By means of Pythagoras' theorem providing you are given the radius and perpendicular height of the cone
Entire surface area of a cylinder = (2*pi*radius^2)+(circumference*height) If you are given the circumference then radius = circumference/2*pi
Easy, you find the area of the circle (Pi X Radius squared) and then multiply it by the height. Your question asks about using the diameter...the radius is half of the diameter.
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
The volume of a cone is 1/3 pi times the radius squared times the height. When given the volume and height divide both sides by the height. Volume divided by height is equal to 1/3 times pi times the radius squared. Now divide both sides by 1/3 pi. This will leave you with the radius squared. Take the square root of both sides and you will get the radius.
If you are referring to a cylinder, the volume is given by the equation: V = pi * r^2 * h where pi = 3.14159265.........., r = radius and h = height
