Answer

The volume of the cylinder is approximately 16,334.28 cubic inches.

Solution

To find the volume of a cylinder, we can use the formula: \[ V = \pi r^2 h \] where: - \( V \) is the volume of the cylinder, - \( r \) is the radius of the cylinder, - \( h \) is the height of the cylinder. Given: - Height (\( h \)) = 18 inches - Radius (\( r \)) = 17 inches Substitute the given values into the formula: \[ V = \pi (17)^2 (18) \] Now, we can calculate the volume using the approximation of \( \pi \) as 3.14 and round the answer to the nearest hundredth. Calculate the value by following steps: - step0: Calculate: \(3.14\times 17^{2}\times 18\) - step1: Multiply the terms: \(56.52\times 17^{2}\) - step2: Rewrite the expression: \(56.52\times 289\) - step3: Multiply the numbers: \(16334.28\) The volume of the cylinder is approximately 16334.28 cubic inches. Rounding this to the nearest hundredth, the volume is 16334.28 cubic inches.

The Deep Dive

To find the volume of a cylinder, you can use the formula: \[ V = \pi r^2 h \] Plugging in the values where \( r = 17 \) inches and \( h = 18 \) inches, we have: \[ V = 3.14 \times (17)^2 \times 18 \] Calculating \( (17)^2 = 289 \): \[ V = 3.14 \times 289 \times 18 \approx 3.14 \times 5202 = 16366.28 \] Rounding to the nearest hundredth, the volume of the cylinder is approximately: **16366.28 cubic inches.** Now, let’s break it down! When working with cylinders, it's essential to remember that volume is all about packing space! You can visualize how much soda or any liquid could fill that cylinder; it's like imagining the joy of a giant soda fountain! And don’t forget to double-check your calculations! A common mistake occurs when people forget to square the radius before multiplying by the height. So, always do the \( r^2 \) step first! A simple misstep can lead you to a much smaller or larger volume than reality.
