total surface area of a balloon = 4πr²
total surface area of 72 balloon = 44352
72×4πr² = 44352
r = 7
volume of ethane gas used = 72 ×4/3πr³
volume of gas = 72×4×22×7×7/3 = 103488 cm³
total surface area of 72 balloon = 44352
72×4πr² = 44352
r = 7
volume of ethane gas used = 72 ×4/3πr³
volume of gas = 72×4×22×7×7/3 = 103488 cm³
