The ratio of the Volume of the sphere whose radius are in ratio 1:2 is 1:8, the correct option is C.
A sphere is a three dimensional figure, it is made of set of points that are all equidistant from the center.
The ratio of radii of two spheres is 1:2
Volume of a sphere is given by
V = (4/3) πr³
The ratio of two sphere is given by
V₁ / V₂ = (r₁/r₂)³
V₁ / V₂ = (1/2)³
V₁ / V₂ = 1/8
Therefore, the ratio of the Volume of the sphere whose radius are in ratio 1:2 is 1:8, the correct option is C.
