Q. What is the volume of a cylinder with a height of 9.9m and a base with a diameter of 5.2m, to the nearest tenth of a cubic meter?Answer: m3
Identify formula for volume: 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 base radius: Calculate the radius of the base of the cylinder.The diameter of the base is given as 5.2 meters. The radius is half of the diameter, so r=2diameter=25.2m=2.6m.
Substitute radius and height: Substitute the radius and height into the volume formula.Using the radius of 2.6 meters and the height of 9.9 meters, the volume V is calculated as V=π×(2.6m)2×9.9m.
Perform volume calculation: Perform the calculation for the volume. V=π×(2.6m)2×9.9m=π×6.76m2×9.9m≈3.14159×6.76m2×9.9m.
Complete final rounding: Complete the calculation and round to the nearest tenth. V≈3.14159×6.76×9.9≈209.937m3.When rounded to the nearest tenth, the volume is approximately 209.9m3.
