HELP GEOMETRY!!!!!! The newest feature at the Great Park is the big orange balloon. The volume of this perfectly spherical ballo

WITCHER [35]

Answer: 8.3 ft

Step-by-step explanation:

Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.

Since, the volume of a sphere, $V= \frac{4}{3} \pi r^3$

Where r is the radius of the sphere.

Here V= 2361.7 cubic feet

Therefore, $2361.7=\frac{4}{3} \pi r^3$

⇒ $r^3= \frac{21\times 2361.7}{88}$

⇒ $r= 563.5875^{1/3}=8.2601344693$ ≈8.3 feet

Thus, the radius of the sphere = 8.3 feet
