Q. What is the volume of a cylinder, in cubic feet, with a height of 4 feet and a base diameter of 4 feet? Round to the nearest tenths placeAnswer: V=□ feet 3
Identify Formula: Identify the formula for the volume of a cylinder.The formula for the volume of a cylinder is V=πr2h, where V is the volume, 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.Since the diameter of the base is given as 4 feet, the radius r is half of the diameter. Therefore, r=2diameter=24 feet=2 feet.
Substitute Values: Substitute the values of the radius and height into the volume formula.Using the radius r=2 feet and height h=4 feet, the volume V is calculated as follows:V=π×(2 feet)2×4 feet
Calculate Volume: Calculate the volume using the values substituted in the formula.V=π×4 square feet×4 feetV=π×16 square feet×4 feetV=π×64 cubic feet
Use Numerical Value: Use the value of π (approximately 3.14159) to calculate the volume numerically.V≈3.14159×64 cubic feetV≈201.06176 cubic feet
Round Volume: Round the volume to the nearest tenths place. The volume, rounded to the nearest tenths place, is approximately 201.1 cubic feet.
