The radius of cone-shaped sculpture is 4.582575695.
What is cone?
A cone is "three dimensional shape that narrows smoothly from a flat base to a point".
According to the question,
The sculpture is in cone shape which has 5 feet tall and has total volume of cone 109.9 cubic feet.
Formula for volume of cone = \(\frac{1}{3}\) π.r².h
109.9 = \(\frac{1}{3}\) ×\(\frac{22}{7}\) × r² ×5
109.9 = (110/21) .r²
109.9 × \(\frac{21}{110}\) = r²
\(\frac{2307.9}{110}\) = r²
20.981 = r²
r =4.582575695... ≈ 4.59.
Hence, the radius of cone-shaped sculpture is 4.582575695.
