Answer:
The volume of a sphere can be calculated using the formula:
V = (4/3)πr^3
where V is the volume, π is the mathematical constant pi, and r is the radius of the sphere.
Since the diameter of the beach ball is given as 30 cm, the radius (r) can be calculated by dividing the diameter by 2:
r = 30 cm / 2 = 15 cm
Substituting this value of r into the formula, we get:
V = (4/3)π(15 cm)^3
V = (4/3)π(3375 cm^3)
V = 4.5π(3375 cm^3)
V = 14137.5 cm^3 (rounded to one decimal place)
Therefore, approximately 14,138 cubic centimeters of air are needed to fill the beach ball.
