A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?

Alenkasestr [34]

To solve for the mass of a substance is to simply get the product of volume and density, that is:

mass = density * volume

So calculating for mass:

mass = (2.76 g / cm^3) * 6 cm^3

What is the length of side BC of the triangle? Enter your answer in the box.

kondor19780726 [428]

The triangle is an equiangular triangle so that means it must be an equilateral triangle.

3x - 3 = x + 8

2x = 11

x = 5.5

BC = 3(5.5) - 3

BC = 13.5

Answer:

$V=1071.78\ cm^3$

Step-by-step explanation:

Given that,

The radius of the cone, r = 8 cm

The height of the cone, h = 16 cm

We need to find the volume of the cone. The formula for the volume of the cone is given by :

$V=\dfrac{1}{3}\pi r^2 h\\\\=\dfrac{1}{3}\times 3.14\times 8^2\times 16\\\\V=1071.78\ cm^3$

So, the volume of the cone is equal to $1071.78\ cm^3$ .
