cone
radius= 3cm
height=14cm
what is the volume?
how do you do this
The formula is:
V =1/3 * pi * r^2 * h
V = 1/3 * 3.14 * 9 * 14
V = ?

To find the volume of a cone, you need to use the formula:
Volume = (1/3) * π * r^2 * h
where:
- π is approximately 3.14159
- r is the radius of the base of the cone
- h is the height of the cone
In your case, the radius is given as 3 cm and the height is given as 14 cm.
So, to find the volume, substitute the values into the formula:
Volume = (1/3) * 3.14159 * (3 cm)^2 * 14 cm
Now, let's calculate it step by step:
1. Square the radius: (3 cm)^2 = 9 cm^2
2. Multiply the square of the radius by the height: 9 cm^2 * 14 cm = 126 cm^3
3. Multiply the result by 1/3: (1/3) * 126 cm^3 ≈ 42 cm^3
Therefore, the volume of the cone is approximately 42 cm^3.
