Let the cylinder have radius R and height h
Let the cone have radius r and same height h
Then:
Volume cylinder = πr²h
Volume cone = ⅓πR²h
If the volume are equal:
⅓πR²h = πr²h
→ ⅓R² = r²
→ R² = 3r²
→ R = √3 r
→ ratio radii cone : cylinder = 1 : √3
Let the radius of the first be 2r; then the radius of the second is 3r Let the height of the first be 5h; then the height of the second is 4h volume cylinder = π × radius² × height → volume first = π × (2r)² × 5h = 20πr²h → volume second = π × (3r)² × 4h = 36πr²h → ratio of their volumes is: 20πr²h : 36πr²h = 20 : 36 (divide by πr²h) = 5 : 9 (divide by 4)
ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
The rate of diffusion would be faster for the right cylinder.
C- The rate of diffusion would be faster for the right cylinder

2*(r+h)/rh where r is the radius and h the height of the cylinder.
If the ratio of the radii is 1:3 then the ratio of volumes is 1:27.

ratio of volumes is the cube of the ratio of lengths radii (lengths) in ratio 3 : 4 → volume in ratio 3³ : 4³ = 27 : 64
It depends on the ratio between the base and the height. Bh=A, and B=(pi)(r2)
Volume of a sphere of radius r: V = 4pi/3 x r3 If the ratio of the radii of two spheres is 23,then the ratio of their volumes will be 233 = 1,2167
No. To be similar ALL lengths must be in the same ratio. If two cylinders have the same radii, but different heights then the radii have one ratio (1:1) but the heights have a different ratio; thus they are not similar.
volume = pi * radius2 * heightThere are three unknowns in this equation, V, r, and h, and you only know v. You need to provide additional information (such as the height of the cylinder or some ratio of height to width) in order to solve
ratio would also be 2 since the volume of a sphere is 4/3(pie)r(cubed) and since both 4/3 and pie are constants the variable is the radius of the spheres and as such the ratio of the radii would be equal to that of the volumes.
