Q. What is the volume of a cylinder with a height of 11.7in and a base with a diameter of 10.6in, 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 10.6 inches. The radius is half of the diameter, so r=diameter/2=10.6 inches/2.
Perform calculation: Perform the calculation for the radius. r=210.6inches=5.3inches.
Substitute values: Substitute the radius and height into the volume formula.Using the radius r=5.3 inches and height h=11.7 inches, the volume formula becomes V=π×(5.3 inches)2×11.7 inches.
Calculate volume: Calculate the volume using the substituted values.V=π×(5.3inches)2×11.7inches=π×28.09inches2×11.7inches.
Perform multiplication: Perform the multiplication to find the volume.V≈3.14159×28.09 inches2×11.7 inches=1031.0173 cubic inches.
Round volume: Round the volume to the nearest tenth of a cubic inch. V≈1031.0 cubic inches.
