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

EXPLANATION
The equation of a parabola in factored form is
where 'a' is the leading coefficient and 'm' and 'n' are the zeros.
From the question, the zeros of the parabola are 6 and −5.
This implies that,
We plug in these zeros to get:
If (-1, 3) is a point on the graph of this parabola,then it must satisfy its equation.
We substitute x=-1 and y=3 to obtain:
The first choice is correct.
