Answer:
45cm
Step-by-step explanation:
If volume of a sphere = 4/3πr³
Volume of hemisphere = 1/2 of volume of a sphere
Volume of hemisphere = 1/2{4/3πr³}
Volume of hemisphere = 2/3πr³
Given the volume of hemisphere = 60,750πcm³
60,750π = 2/3πr³
60,750 = 2r³/3
2r³ = 60,750×3
r³ = 91,125
r = ∛91,125
r = 45cm
Radius of the globe is 45cm
