Beyond the Answer
To determine the height of the cylinder when the area of its base is 150 square inches and its volume is 1,050 cubic inches, we can use the formula for the volume of a cylinder: \( V = \text{Base Area} \times \text{Height} \). Rearranging this gives us the height: \( \text{Height} = \frac{V}{\text{Base Area}} = \frac{1050}{150} = 7 \) inches. So, the height of the cylinder is 7 inches! Leann's cylindrical water tank has a diameter of 3 meters, which means the radius is \( \frac{3}{2} = 1.5 \) meters. The volume of a cylinder is given by \( V = \pi r^2 h \). Plugging in the values, we get: \( V = \pi (1.5)^2 (2) \approx 3.14 \times 2.25 \times 2 \approx 14.13 \) cubic meters. So, the water tank can hold approximately 14.13 cubic meters of water!
