Q. Find the volume of a right circular cone that has a height of 13.4m and a base with a circumference of 13.6m. Round your answer to the nearest tenth of a cubic meter.Answer: m3
Find Radius from Circumference: To find the volume of a cone, we need to know the radius of the base and the height. The formula for the volume of a cone is V=(31)πr2h, where r is the radius and h is the height. We are given the height (13.4m) but only the circumference of the base (13.6m), not the radius. We can find the radius by using the formula for the circumference of a circle, which is C=2πr.
Calculate Radius: First, we need to solve for the radius r using the circumference C=13.6m. The formula for circumference is C=2πr, so we can rearrange it to solve for r: r=2πC.
Calculate Volume with Radius: Now, let's calculate the radius: r=2π13.6m. We can approximate π as 3.14159.
Calculate Volume with Formula: Performing the calculation gives us r=2×3.1415913.6m≈6.2831813.6m≈2.165m.
Round Final Volume: With the radius found, we can now calculate the volume of the cone using the formula V=31πr2h. Plugging in the values, we get V=31×π×(2.165m)2×13.4m.
Round Final Volume: With the radius found, we can now calculate the volume of the cone using the formula V=31πr2h. Plugging in the values, we get V=31×π×(2.165m)2×13.4m.Calculating the volume gives us V=31×3.14159×(2.165m)2×13.4m≈31×3.14159×4.690225m2×13.4m.
Round Final Volume: With the radius found, we can now calculate the volume of the cone using the formula V=31πr2h. Plugging in the values, we get V=31×π×(2.165m)2×13.4m. Calculating the volume gives us V=31×3.14159×(2.165m)2×13.4m≈31×3.14159×4.690225m2×13.4m. Performing the multiplication, we get V≈31×3.14159×62.849015m3≈65.973m3.
Round Final Volume: With the radius found, we can now calculate the volume of the cone using the formula V=31πr2h. Plugging in the values, we get V=31×π×(2.165m)2×13.4m. Calculating the volume gives us V=31×3.14159×(2.165m)2×13.4m≈31×3.14159×4.690225m2×13.4m. Performing the multiplication, we get V≈31×3.14159×62.849015m3≈65.973m3. Finally, we round the volume to the nearest tenth of a cubic meter, which gives us V≈66.0m3.
