Col. A: \(\frac{4}{3}πr^3\)
Col. B: 2000 \(cm^3\)

Multiply both sides by 3:
Col. A: \(4πr^3\)
Col. B: 6000 \(cm^3\)

Divide both sides by 4:
Col. A: \(πr^3\)
Col. B: 1500 \(cm^3\)

Pu, r = 7 m = 700 cm

Col. A: \(π(700)^3\)
Col. B: 1500 \(cm^3\)

Divide both sides by \(700^3\):

Col. A: \(π = 3.14\)
Col. B: \(\frac{1500}{700^3}\)

Col. A > Col. B
Hence, option A
