  1. Write Formula for Volume: First, write down the formula for the volume of a cylinder, which is V=πr2hV = \pi r^2 h.
  2. Plug in Values: Next, plug in the values for the radius r=3.5 ftr = 3.5 \text{ ft} and the height h=29 fth = 29 \text{ ft} into the formula, and use 3.143.14 for π\pi. So, V=3.14×(3.5)2×29V = 3.14 \times (3.5)^2 \times 29.
  3. Calculate Radius Square: Now, calculate the square of the radius: (3.5)2=12.25(3.5)^2 = 12.25.
  4. Multiply by Pi: Then, multiply the squared radius by π\pi: 3.14×12.25=38.4353.14 \times 12.25 = 38.435.
  5. Calculate Volume: Finally, multiply that result by the height of the cylinder to find the volume: 38.435×29=1114.61538.435 \times 29 = 1114.615.
  6. Round to Nearest Whole Number: Round the result to the nearest whole number: 1114.6151114.615 rounds to 11151115.
