Full solution

Q. A cylinder has a base radius of 22 inches and a height of 1414 inches. What is its volume in cubic inches, to the nearest tenths place?\newlineAnswer: V= V= inches 3 ^{3}
  1. Formula Explanation: To find the volume of a cylinder, we use the formula V=πr2hV = \pi r^2 h, where VV is the volume, rr is the radius of the base, and hh is the height of the cylinder.
  2. Calculate Radius Squared: First, we need to square the radius. The radius is 22 inches, so squaring it gives us 22=42^2 = 4 square inches.
  3. Calculate Volume: Next, we multiply the squared radius by the height of the cylinder. The height is 1414 inches, so we calculate 44 square inches ×14\times 14 inches =56= 56 cubic inches.
  4. Multiply by Pi: Now, we need to multiply this result by π\pi (pi), which is approximately 3.141593.14159. So, we calculate 5656 cubic inches ×π56×3.14159\times \pi \approx 56 \times 3.14159.
  5. Final Calculation: Performing the multiplication gives us approximately 175.9324175.9324 cubic inches.
  6. Round to Nearest Tenth: Finally, we round the result to the nearest tenths place, which gives us 175.9175.9 cubic inches.
