10 points for question answered correctly and work shown<br> thanks!
MaRussiya [10]

Answer:

Part 1 - A

Answer: 301.592895 m^3

Step-by-step explanation:

The formula for the volume of a cone is calculated the formula:

<u>V = πr^2h/3  </u>

In the question, we are given the value of the radius and height in meters through which we can calculate the volume.

r = 6

h = 8

and we know the value of π to be 22/7, or 3.14285714286.

By substituting these values in the formula, we can solve for volume of the cone:

V = π (6)^2 8 / 3  

Volume = 301.592895 m^3

Hope this helps!
