Q. What is the volume, in cubic feet, of a cylinder with a height of 17 feet and a base radius of 8 feet, to the nearest tenths place?Answer: V=□ feet 3
Given Data: To find the volume of a cylinder, we use the formula V=πr2h, where V is the volume, r is the radius of the base, and h is the height of the cylinder. We are given the radius r=8 feet and the height h=17 feet.
Calculate Base Area: First, we calculate the area of the base of the cylinder, which is a circle. The area A of a circle is given by the formula A=πr2. Substituting the given radius, we get A=π(8 feet)2.
Multiply Base Area and Height: Calculating the area of the base, we have A=π(64 feet2)=64π feet2.
Calculate Volume: Next, we multiply the area of the base by the height of the cylinder to find the volume. So, V=64π feet2×17 feet.
Approximate Volume with π: Performing the multiplication, we get V=1088π cubic feet.
Calculate Approximate Volume: To express the volume to the nearest tenths place, we need to use the approximate value of π, which is 3.1416. So, V≈1088×3.1416 cubic feet.
Round to Nearest Tenth: Calculating the approximate volume, we get V≈3419.5328 cubic feet.
Round to Nearest Tenth: Calculating the approximate volume, we get V≈3419.5328 cubic feet.Rounding to the nearest tenths place, the volume of the cylinder is approximately 3419.5 cubic feet.
