The capacity of a cylinder tank is 8316 cm3. If the radius of its base is 21 cm, then find the depth of the tank.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 6 cm.
The capacity of a cylindrical tank is given by the formula:
Capacity = π × radius × height
8316 = π × 21 × height
height = 8316 / (π × 21)
Calculating the value:
height ≈ 6 cm
Therefore, the depth of the tank is approximately 6 cm.
