Question

What is the volume of the cone with diameter 4 ft and height 4 ft? Round to the nearest cubic foot.

Answer 1

Answer:

V = 67.0206 m3

Step-by-step explanation:

Answer 2

Answer: $17ft^3$

Step-by-step explanation:

The volume of a cone can be calculated with the following formula:

$V_{(cone)}=\frac{1}{3}\pi r^2h$

Where "r" is the radius and "h" is the height.

The radius is half the diameter, then "r" is:

$r=\frac{4ft}{2}\\\\r=2ft$

Since we know that radius and the height, we can substitute them into the formula.

The volume of the cone  to the nearest cubic foot is:

 $V_{(cone)}=\frac{1}{3}\pi (2ft)^2(4ft)$

 $V_{(cone)}=17ft^3$
