Explanation

Volume of a cylinder = πr²h First convert 3 m to cm by multiplying by 100 Volume of External cylinder = π × 13² × 300 Volume of Internal cylinder = π × 10² × 300 Hence; Volume of External cylinder - Volume of Internal cylinder Total volume (v) = π(169 − 100) × 300 V = π × 69 × 300 V = 20700π cm³
