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)

339.1 inches3

24,416.7 inches3

113.0 inches3

3,052.1 inches3

Answer 1

Volume of a sphere: V = (4/3)πr^3. Here r = 9 in, so
V = (4/3)(3.14)(9^3) = (4/3)(3.14)(729) = 3052.08 ≈ 3052.1 in^3.

Answer: 3,052.1 inches^3
