Correct Answer
B. 314Explanation
The correct answer is 314. To calculate the volume of a cone, we use the formula V = (1/3) * π * r^2 * h, where r is the radius and h is the height. Given that the diameter is 10 cm, the radius is half of that, which is 5 cm. Substituting the values into the formula, we get V = (1/3) * 3.14 * 5^2 * 12 = 314 cm^3. Therefore, the volume of the cone is 314 cm^3.Rate this question:

C. 192Explanation
The given information states that the base of the prism is a rhombus with diagonal lengths of 8 cm and 6 cm. The area of the lateral surface of the prism is given as 160 cm2. To find the volume of the prism, we need to multiply the area of the base by the height. Since the base is a rhombus, we can use the formula for the area of a rhombus, which is 1/2 times the product of the diagonals. In this case, the area of the base is (1/2) * 8 cm * 6 cm = 24 cm2. To find the height, we divide the given area of the lateral surface by the perimeter of the base, which is 160 cm2 / (2 * (8 cm + 6 cm)) = 160 cm2 / 28 cm = 5.71 cm. Finally, we calculate the volume by multiplying the base area by the height, which is 24 cm2 * 5.71 cm = 137.04 cm3. Since the answer choices are not in decimal form, we round the volume to the nearest whole number, which is 137. The correct answer should be 192.Rate this question:

Correct Answer
A. 154Explanation
The volume of a cylinder can be calculated using the formula V = πr^2h, where r is the radius of the cylinder and h is the height. In this case, the diameter is given as 7 cm, so the radius would be half of that, which is 3.5 cm. The height is given as 4 cm. Plugging these values into the formula, we get V = 3.14 * (3.5)^2 * 4 = 3.14 * 12.25 * 4 = 154. Therefore, the volume of the cylinder is 154.Rate this question:
