Answer:
7- 780 m
8- 9,459 cm
9- 864 cm
10- 151 in
Explanation:
7- The volume of a rectangular pyramid is:
We just have to substitute the values:
8- The volume of a cone is:
Let's substitute the values and solve:
If you want to round it, the answer will be:
9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.
So,
10- The volume of the cone is V = hπr² / 3
Then,
9 is the diameter, which is the radius two times. As you see, what the formula asks is for the radius at the second power -multiplied by itself two times-, but if we get the diameter value instead, there is no need to multiply it. The diameter stays the same.
If you want to round it to the nearest tenth, the answer is:
