Answer:

35 cubic inches

Step-by-step explanation:

The volume of a pyramid is $\frac{1}{3} bh$ , where b = base and h = height. To find the area of the base, we multiply 3 by 5 and then divided by 2.

3 × 5 = 15
15 ÷ 2 = 7.5

Next, we multiply 7.5 by 14.

7.5 × 14
105

Lastly, we divide by 3.

105 ÷ 3
35

Therefore, the answer is 35 cubic inches.

Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
