Answer:
115.625 cm³
Step-by-step explanation:
The ratio of the volumes is in proportion with the cube of the proportion of the lengths.
V1/925 = (10/20)³
V1/925 = (1/2)³
V1/925 = 1/8
V1 = 925 ÷ 8
V1 = 115.625 cm³
Answer:
115.625 cm³
Step-by-step explanation:
For 2 similar shapes
linear ratio = a : b, then
volume ratio = a³ : b³
The ratio of the radii = 20 : 10 = 2 : 1, thus
The ratio of the volumes = 2³ : 1³ = 8 : 1
Let x be the volume of the smaller cone, then
[tex]\frac{x}{1}[/tex] = [tex]\frac{925}{8}[/tex] ( cross- multiply )
8x = 925 ( divide both sides by 8 )
x = 115.625
The volume of the smaller cone = 115.625 cm³
