volume of a sphere =4/3πr³
4/3πr³= 38808
r³=38808x7x3/4x22
r=21 cm
Surface area = 4πr²
=4×22/7×21×21
=5544 cm²

=>volume of a metallic sphere = 4/3πr³ = 38808 cm³
=>4/3πr³ = 38808 cm³
=>r³ = 38808 ×3/4 ×7/22
=>r³ =9261
=>r =(9261)⅓
=>r = 21 cm
=>Surface area = 4πr²
=>Surface area= 4 ×22/7 ×21×21
=>Surface area=5544cm²
=>4/3πr³ = 38808 cm³
