Shakira is making a round piñata for a celebration. Her plan is to fill the inside with confetti. If the piñata measures 18 inches in diameter, what is its volume using 3.14 for pi and rounded to the nearest tenth?(1 point)

1 answer

The volume of a sphere is given by the formula V = 4/3 * pi * r^3, where r is the radius of the sphere.

Since the piñata has a diameter of 18 inches, the radius is half of that, which is 18/2 = 9 inches.

Now, calculate the volume:

V = 4/3 * 3.14 * (9)^3
V = 4/3 * 3.14 * 729
V = 12.56 * 729
V = 9152.24

Rounded to the nearest tenth, the volume of the piñata is 9152.2 cubic inches.
