1/4. and. 1/12. will do that.

**Answer:**

2,250

**Step-by-step explanation:**

negative times a negative equals a positive.

**Answer:**

The volume for a cylinder is computed as follows:

V = π*r²*h

where r is the radius and h the height

In the following table some values for r and h are assumed and the volume is computed (I cannot compare the results with the tool because I don't know which tool are you talking about)

radius (ft) height (ft) volume (ft³)

1 1 V = π*1²*1 = π ≈ 3.141

2 1 V = π*2²*1 = 4π ≈ 12.566

1 2 V = π*1²*2 =2π ≈ 6.283

2 2 V = π*2²*2 = 8π ≈ 25.132

3 1 V = π*3²*1 = 9π ≈ 28.274

1 3 V = π*1²*3 = 3π ≈ 9.424

3 3 V = π*3²*3 = 27π ≈ 84.823

Letter c makes more sense
