Answer:

Step-by-step explanation:

The formula for determining the volume of a sphere is given as

Volume = (4/3) πr³

where r is the radius and π is a constant whose value is 3.14

From the information given,

Diameter = 9.4 mm

Radius = diameter/2 = 9.4/2

= 4.7 mm

Volume of sphere = 4/3 × 3.14 × 4.7³

= 434.67 mm³

The formula for determining density is expressed as mass/volume

Mass = 3.475 g

Density = 3.475/434.67 = 0.008g/mm³

Find the volume of the cone.
Ne4ueva [31]

Answer:

3142.86 cubic cm

Step-by-step explanation:

volume of cone is given by formula

volume of cone = 1/3(area of base*height)

Given radius of base = 10cm

we know area of circle is given by \pi  r^2 where r is radius of circle

thus area of base of cone is calculated below

\pi 10^2\\=> 22/7 *100\\=> 314.2857

area of base of cone is 314.2857 square cm

height = 30 cm

Thus volume of cone  = 1/3* (area of base*height)

                                   = 1/3(314.2857*30)

                                   = 1/3 *9428.571 = 3142.857.

Thus, volume of cone is 3142.857 cubic cm.

volume of cone  to the nearest hundredth is 3142.86 cubic cm
