Answer:
523.3ft³
Step-by-step explanation:
Given
Diameter, D = 10ft
Required
Determine the volume of helium it can hold.
To solve this, we simply calculate the volume of a sphere, which is:
V = 4/3πr³
Where
r = ½D
r = ½ * 10ft
r = 5ft
Substitute 5 for r in the stated formula and take π as 3.14
V = 4/3 * 3.14 * 5³
V = 4/3 * 3.14 * 125
V = ⅓(4 * 3.14 * 125)
V = ⅓ * 1570
V = 523.3 ft³
Hence, the sphere can contain 523.3ft³ of helium
