20.41 cubic feet
-
10.205 cubic feet
-
5.1625 cubic feet
-
10.205 square feet
Correct Answer
A. 10.205 cubic feetExplanation
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 2.0 ft, so the radius would be 1.0 ft (half of the diameter). Plugging in the values, we get V = π(1.0 ft)^2(3.25 ft) = 10.205 cubic feet. Therefore, the correct answer is 10.205 cubic feet.Rate this question:

A concrete slab has a width of 7.5 ft, a depth of 4.2 ft, and a height of 0.5 ft. What is the surface area of the slab?
-
37.35 square feet
-
74.7 square feet
-
15.75 square feet
-
31.5 feet
Correct Answer
A. 74.7 square feetExplanation
The surface area of a rectangular prism can be found by multiplying the length, width, and height of the prism. In this case, the width is 7.5 ft, the depth is 4.2 ft, and the height is 0.5 ft. Multiplying these values together gives 7.5 ft * 4.2 ft * 0.5 ft = 15.75 cubic feet. However, the question asks for the surface area, not the volume. To find the surface area, we need to find the area of each face and add them together. The slab has 6 faces, with 2 faces having an area of 7.5 ft * 4.2 ft = 31.5 square feet, 2 faces having an area of 7.5 ft * 0.5 ft = 3.75 square feet, and 2 faces having an area of 4.2 ft * 0.5 ft = 2.1 square feet. Adding these areas together gives a total surface area of 31.5 square feet + 31.5 square feet + 3.75 square feet + 3.75 square feet + 2.1 square feet + 2.1 square feet = 74.7 square feet.Rate this question:

-
1
-
2
-
3
-
4
Correct Answer
A. 3Explanation
If a single mate constraint is applied between two opposing surfaces in an assembly, three degrees of freedom will remain between the two parts. A mate constraint typically constrains the movement of the parts in the direction perpendicular to the mating surfaces, but it allows rotation around and translation along the axis perpendicular to the mated surfaces.
Here are the remaining degrees of freedom:
Translation along the axis perpendicular to the mating surfaces.
Rotation around the axis perpendicular to the mating surfaces.
Rotation around an axis in the plane of the mating surfaces.Rate this question:
