Less than 90° = acute
more than 90° = obtuse
equal to 180° = straight
more than 360° = reflex
Hello!

The volume of the square pyramid is approximately 
____________________________________________________________

V = 

First, we must find the area of the square base.
A = l * w
A = 3.5 * 3.5
A = 12.25 km^2
The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.
V = (12.25 * 4.7) / 3
V = 19.1916666667
V ≈ 19.19 km^3
Use the option number 5 and draw a parallel and perpendicular line across to make the slope of the lines collapse
Answer:
Then it would be the other way around 19 ≥ k + 6
