The volume of a pyramid varies jointly as the height and the area of the base. If a pyramid has the measurements V=1144

Naddika [18.5K]

Answer:

11040 m³
k ≈ 0.33
V = (1/3)Bh

Step-by-step explanation:

The given relation is ...

V = kBh . . . . . for some base area B, height h, and constant of variation k

We are given length and width of the base so we presume it is a rectangle.

B = l·w = 8·11 = 88 . . . . square meters

The given volume tells us the value of k:

1144 = k(88)(39) . . . . . . cubic meters

1144/3432 = k = 1/3 ≈ 0.33

The value of k is about 0.33.

Then the volume of the larger pyramid is ...

V = (1/3)(15 m)(46 m)(48 m) = 11,040 m³

The general relationship is ...

V = 1/3Bh

Igoryamba

Answer:

$cos(\alpha)=\frac{3}{5}=0.6$

$cosec(\alpha)=\frac{5}{4}=1.25$

Step-by-step explanation:

El cos(α) se define como el cociente entre el cateto adyacente y la hipotenusa.

El valor del cateto adyacente en nuestgro caso es CA = 3.

La hipotenusa se calcual de la siguiente manera:

$h=\sqrt{3^2+4^2}=5$

Por lo tanto, el cos(α) sera:

$cos(\alpha)=\frac{3}{5}=0.6$

El cosec(α)=h/CO.

El cateto opuesto CO = 4 y la hipotenusa h = 5

Por lo tanto, el cosec(α) sera:

$cosec(\alpha)=\frac{5}{4}=1.25$
