Volume of cone=4034.66cm^3
Pi×r^2×h/3=4034.66
Pi×13×13×h=4034.66×3
22×13×13×h/7=4034.66×3
h=4034.66×3×7/13×13×22
h=45.57
So h=45.6cm
As x approaches 3 from the right, the limit is 3. There is a closed hole up there AT x=3 y=7, but we don't care about what happens AT x=3, only what happens as x APPROACHES 3.
1 milliliter = 0.001 liters
400 milliliters = 0.4 liters
Therefore, 4 liters is greater than 400 milliliters
