1,200 is the correctly nearest . We round 1,210 to 1,200
Answer:volume of regular pyramid = 3388 units³
Explanation:Volume of regular pyramid can be calculated using the following rule:
volume of regular pyramid =

* area of base * height
volume of regular pyramid =

* length * width * height
Based on the comment you added above, we have:
length = 11 units
width = 11 units
height = 84 units
Substitute with the givens in the above equation to get the volume as follows:
volume =

* 11 * 11 * 84
volume = 3388 units³
Hope this helps :)
Answer:
F. 82
Step-by-step explanation:
To calculate the length of BC, Pythagoras theorem will be used.
It says, Hypotenuse^2 = Perpendicular^2 + Base^2
In our case, Perpendicular = AB = 18 and Base = AC = 80
therefore,
Hypotenuse^2 = 18^2 + 80^2 = 6724
Hypotenuse = BC =
= 82
