A Correct answer
Explanation

Volume of a sphere = 4/3 * pi * r^3. V = 4/3 * 3.14 * (0.63)^3 = 4/3 * 3.14 * 0.250047 = 1.047... which is 1.05.

AI explanation

Using the volume of a sphere formula, V = (4/3) * pi * r^3, substitute the given radius of 0.63 m. Approximating pi as 22/7, the calculation becomes (4/3) * (22/7) * 0.63 * 0.63 * 0.63. Multiplying these values gives a volume of approximately 1.05 cubic meters.
