What is the ratio of radii of 2 spheres if the ratio of their voumes is 2?

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.

The ratio between the radii of two spheres is 9 2 What is the ratio of their volumes?
729/8
What is the similarity ratio of two spheres with volumes of 20 pi m3 and 160 pi m3.?
The similarity ratio of the two spheres can be found by taking the cube root of the ratio of their volumes. The volume of the first sphere is 20pi m^3 and the volume of the second sphere is 160pi m^3. The cube root of the ratio of their volumes is (160pi/20pi)^(1/3) = (8)^(1/3) = 2. Therefore, the similarity ratio of the two spheres is 2:1.
How do I find if 2 D shapes are similar?
They must have all angles which are the same, all of whose straight lines are in the same ratio and whose curves have radii of curvature in the same ratio.
What is the sum of radii?
2 radii = one diameter
What is the radius x of a cone with height 2 units if a similar cone has radius of 4 units and height of 10 units?
If two shapes are similar, then each length is in the same ratio. The ratio of the heights is 10 : 2 Thus the radii are in the same ratio, ie 4 : x = 10 : 2 → x = 2 × 4 ÷ 10 = 0.8 units

What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 2 7?
It is 8 : 343.
What is the ratio for the volumes of two similar spheres given that the ratio of their radii is 27?
If the ratio is 2 : 7 then the volumes are in the ratio 8 : 343.
What is the ratio of the circumferences of two wheels if the ratio of their radii is 2 to 3?
The ratio of all lengths is the same. The ratio of the circumferences = ratio of the radii = 2:3
If the ratio between the radii of the two spheres is 5 8 what is the ratio of their volumes?
Ratio of volumes is 53 to 83 which is 125 to 512
What is the similarity ratio of two spheres with volumes of 20 pi m3 and 160 pi m3.?

The volume of the first sphere is 20pi m^3 and the volume of the second sphere is 160pi m^3. The cube root of the ratio of their volumes is (160pi/20pi)^(1/3) = (8)^(1/3) = 2. Therefore, the similarity ratio of the two spheres is 2:1.

What is the relationship between area of a circle and its radius squared for a series of circles with large increasingly large radii?
The area of a circle is directly proportional to the square of its radius. If two circles have radii R1 and R2 , then the ratio of their areas is ( R1/R2 )2
What is the radius x of a cone with height 2 units if a similar cone has radius of 4 units and height of 10 units?
If two shapes are similar, then each length is in the same ratio. The ratio of the heights is 10 : 2 Thus the radii are in the same ratio, ie 4 : x = 10 : 2 → x = 2 × 4 ÷ 10 = 0.8 units
How much would a person weighing 100lbs weigh on Neptune?
About 114 lbs at the surface. From Wikipedia, the ratio of the mass of Neptune to the mass of Earth is about 17.15, while the ratio of the radii is about 3.88 (at the equator). The new weight will then be Wneptune = Wearth (17.15) / (3.88^2).
How many radii of a circle will equal its circumference?
Well, the equation for finding the circumfrence of a circle is (diameter)(pi). That is diameter times pi. since the diameter of a circle is 2 radii, we can say that there is 2(pi) radii in a circle.
