Asphere with a mass of 12g has a radius measuring 2 cm. what is it’s density? 3 a. 0.36 g/cm 3 b. 1.43 g/cm 3 c. 6 g/cm 3 d. 24 g/cm

Step-by-step explanation:

A. 0.36 g/cm³

Explanation:

Density = mass/volume

We know the mass, but we must calculate the volume.

The formula for the volume of a sphere is

V = ⁴/₃πr³

r = 2 cm

V = ⁴/₃π × 2³

V = (4π×8)/3

V = (32π)/3

V = 33.5 cm³

Calculate the density

Density = 12/33.5

Density = 0.36 g/cm³

The density of the sphere is 0.36 g/cm³.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
