Answer:
275 ft³
Step-by-step explanation:
Given the ratio of radii of 2 similar figures = a : b , then
ratio of volumes = a³ : b³
Here the ratio of radii = 5 : 2 , so
ratio of volumes = 5³ : 2³ = 125 : 8
Calculate the volume (V) of A using proportion
=
=
( cross- multiply )
V = 275 ft³
That is the volume of figure A = 275 ft³
Answer:
The percent of change in 6 yards to 36 yards is 500% .
Step-by-step explanation:
Formula
Where
Change in value = Final value - initial value
As given
The percent of change in 6 yards to 36 yards.
Final value = 36 yards
initial value = 6 yards
Change in value = 36 - 6
= 30 yards
Put in the formula
Percentage = 500%
Therefore the percent of change in 6 yards to 36 yards is 500% .
