Answer 1

Answer:

7- 780 m

8- 9,459 cm

9- 864 cm

10- 151 in

Step-by-step explanation:

7- The volume of a rectangular pyramid is:

• V=(l x w x h) / 3

We just have to substitute the values:

• V= 13×12×15 / 3
• V= 780 m

8- The volume of a cone is:

• V=hπr² / 3

Let's substitute the values and solve:

• 24×π×19.4² / 3
• 9,458.9

If you want to round it, the answer will be:

• 9,459 cm

9- The volume of a square pyramid V = a²h / 3, where a is the base and h the height.

So,

• V= 12²×18 / 3

• 864 cm

10- The volume of the cone is V = hπr² / 3

Then,

• V= 16×9×π / 3

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.

• V= 150.7

If you want to round it to the nearest tenth, the answer is:

• 151 in.

Hope this helps!!
