Q. What is the volume of a cylinder with a height of 5.5in and a base with a diameter of 11.4in, to the nearest tenth of a cubic inch?Answer: in3
Identify Formula: Identify the formula for the volume of a cylinder.The formula for the volume of a cylinder is V=πr2h, where r is the radius of the base and h is the height of the cylinder.
Calculate Radius: Calculate the radius of the base of the cylinder.The diameter of the base is given as 11.4 inches. The radius is half of the diameter, so r=2diameter=211.4 inches.
Perform Calculation: Perform the calculation for the radius. r=211.4inches=5.7inches.
Substitute Values: Substitute the radius and height into the volume formula.Using the radius r=5.7 inches and height h=5.5 inches, the volume formula becomes V=π×(5.7 inches)2×5.5 inches.
Calculate Volume: Calculate the volume using the values for radius and height. V=π×(5.7inches)2×5.5inches=π×32.49inches2×5.5inches.
Perform Multiplication: Perform the multiplication to find the volume.V=π×32.49inches2×5.5inches≈3.14159×32.49inches2×5.5inches≈592.65215cubic inches.
Round Volume: Round the volume to the nearest tenth of a cubic inch.V≈592.7 cubic inches (rounded to the nearest tenth).
