Answer:
35 cubic inches
Step-by-step explanation:
The volume of a pyramid is , 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:
Step-by-step explanation:
The volume of a cylinder is:
where is the radius and
is the height.
The height is 4 inches greater that the radius, so:
Substituting this in the formula for volume:
the volume is
thus:
Dividing everything between pi:
We can see that the solution for this is
since
We have the radius, now we find the height:
