A cylindrical tank has a capacity of 6160m3. What is the depth of the tank if the radius of its base is 28cm?
8.0m
7.5m
5.0m
2.5m
Explanation
Using \(V = \pi r^2 h\)
6160 = 22/7 x 28 x 28 x h
\(h = \frac{6160}{22 \times 4 \times 28} \)
\(h = 2.5m \)
6160 = 22/7 x 28 x 28 x h
\(h = \frac{6160}{22 \times 4 \times 28} \)
\(h = 2.5m \)
