Q. Find the volume of a right circular cone that has a height of 14.2m and a base with a radius of 16m. Round your answer to the nearest tenth of a cubic meter.Answer: m3
Plug values into formula: The formula to calculate the volume of a right circular cone is V=31πr2h, where r is the radius of the base and h is the height of the cone. We are given that the radius r is 16 meters and the height h is 14.2 meters. Let's plug these values into the formula.
Calculate base area: First, calculate the area of the base (which is a circle) using the formula A=πr2. The radius r is 16 meters, so A=π(16)2.
Compute base area: Now, compute the area of the base: A=π(16)2=π(256). We will use the value of π as approximately 3.14159 for this calculation.
Calculate cone volume: Next, calculate the volume of the cone using the volume formula V=31πr2h. We already have the area of the base A=π(256), so we can substitute this into the formula and multiply by the height h, which is 14.2 meters: V=31π(256)(14.2).
Perform multiplication: Perform the multiplication to find the volume: V=(31)×3.14159×256×14.2. First, calculate 256×14.2=3635.2.
Multiply by pi: Now, multiply this result by π: 3635.2×3.14159≈11426.5.
Divide by 3: Finally, divide by 3 to get the volume of the cone: V≈11426.5/3≈3808.8333 cubic meters.
Round to nearest tenth: Round the volume to the nearest tenth of a cubic meter: V≈3808.8m3.
