Abigail is making a party hat in the shape of a cone for mayas birthday. The hat has a height of 30 in, and a diameter of 20in. What is the approximate volume of the party hat
To calculate the volume of a cone, you can use the formula: V = (1/3) * π * r^2 * h, where V is the volume, π is a mathematical constant (approximately 3.14), r is the radius, and h is the height.
We know the diameter is 20 inches, so the radius is half of that, which is 10 inches.
The height of the party hat is given as 30 inches.
Using the formula: V = (1/3) * 3.14 * 10^2 * 30, we can calculate the volume.
V = (1/3) * 3.14 * 100 * 30
V = (1/3) * 3.14 * 3000
V ≈ 3.14 * 1000
V ≈ 3140
Therefore, the approximate volume of the party hat is 3140 cubic inches.
