Answer:
Volume of the cone is approximately 0.8 cubic meters
Step-by-step explanation:
Recall that the volume of a circular cone is defined by:
where R is the radius of the cone's base, and H the cone's height. Since we have the information of the height H (5.7 m) we just need to find the radius R. We can do such by using the other piece of information: the circumference of its base.
The circumference of a circle is the product:
So by knowing the circumference's length (2.3 m) we can solve for the radius R:
We can now use this result in the formula for the volume:
which can be rounded to the nearest tenth as:
