### A drum cylinder serves as a storage vessel for used grease at a restaurant. The cylinder has a height of 3.25 feet and a diameter of 2.0 ft. What is the volume of the cylinder?

• A.

20.41 cubic feet

• B.

10.205 cubic feet

• C.

5.1625 cubic feet

• D.

10.205 square feet

B. 10.205 cubic feet
Explanation
The volume of a cylinder can be calculated using the formula V = Ï€r^2h, where V is the volume, r is the radius, and h is the height. In this case, the diameter is given as 2.0 ft, so the radius is 1.0 ft (half of the diameter). The height is given as 3.25 ft. Plugging these values into the formula, we get V = Ï€(1.0^2)(3.25) = 3.14159(1.0)(3.25) = 10.205 cubic feet.

### 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?

• A.

37.35 square feet

• B.

74.7 square feet

• C.

15.75 square feet

• D.

31.5 feet

B. 74.7 square feet
Explanation
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, we get 7.5 ft * 4.2 ft * 0.5 ft = 15.75 cubic feet. However, since we are looking for surface area, we need to find the area of all six sides of the prism. The surface area of a rectangular prism is given by the formula 2lw + 2lh + 2wh. Plugging in the values, we get 2(7.5 ft * 4.2 ft) + 2(7.5 ft * 0.5 ft) + 2(4.2 ft * 0.5 ft) = 74.7 square feet.
