The volume of a cone is one-third of the product of the area of the base times the height, i.e.

(1/3)π(r^2)*h = (1/3)π(3cm)^2 *(8cm) = 75.40 cm^3

Now multiply that by the number of cones: 6 * 75.40 cm^3 = 452.40 cm^3.

Then the answer is 452 cm^3

The volume of soil required to fill the pots will be 452cm^3

Data;

  • Numbers of pots = 6
  • radius = 3cm
  • height = 8cm

Volume of a Cone

The volume of a cone is given by

[tex]v = \frac{1}{3} \pi r^2 h\\[/tex]

Let's substitute the value and solve for the volume of one cone

[tex]v = \frac{1}{3}\pi r^2 h\\v = \frac{1}{3} * 3^2 * 8 * \pi\\v = 75.36cm^3[/tex]

The volume of 6 cones is calculated by

[tex]v = 75.36 * 6\\v = 452.16cm^3[/tex]

The volume of soil required to fill the pots will be 452cm^3
