Final answer:
To find the volume of a right circular cone, first find the radius by dividing the diameter by 2. Then use the formula V=(1/3)πr²h, where r is the radius and h is the height, to find the volume. The volume of the cone is approximately 186.7 cubic meters.
Step-by-step explanation:
To find the volume of a right circular cone, we can use the formula V = (1/3)πr²h, where r is the radius of the base and h is the height of the cone. First, we need to find the radius by dividing the diameter by 2. So, the radius is 4.45 m. Then, we can substitute the values into the formula: V = (1/3)π(4.45 m)²(12 m). Solving this equation will give us the volume of the cone. Rounding the answer to the nearest tenth of a cubic meter, the volume is approximately 186.7 cubic meters.
