Answer:
r = 2.05
Step-by-step explanation:
The volume of a sphere is found using the formula V = 4/3πr³. We know the volume of the object is 36 ft³. Substitute V = 36 and solve by multiplying by the reciprocal of 4/3 and dividing by π. This will isolate r³ and r can be solved for using the cube root.
36 = 4/3πr³
3/4*36 = πr³
108/4 = πr³
27 = πr³
27/π = r³
8.6 = r³
∛8.6 = r
2.05 = r
