Find the capacity in liters of a cylindrical well of radius 1 meter and depth 14 meters
[π = 22/7]
[π = 22/7]
44,000 liters
4,400 liters
440 liters
44 liters
説明
V = πr2h
1m = 100cm
14cm = 1400cm
\(∴V = \frac{22}{7} \times \frac{100x100x1400}{1000}\\
= 44, 000 liters\)
1m = 100cm
14cm = 1400cm
\(∴V = \frac{22}{7} \times \frac{100x100x1400}{1000}\\
= 44, 000 liters\)
