Volume of the pyramid:
V = 1/3 · B · h
B = 8 ft²
tan 30° = height / 7√3
1/√3 = height / 7√3
height = 7 ft
V = 1/3 · 8 · 7 = 18.67 ft³ ≈ 19 ft³
Answer : D ) 19 ft³
Add 't' to both sides. t+r=s
Step-by-step explanation:
The correct answer for this would be B
Answer:
V = 

Step-by-step explanation:
Volume of a cone is:

Substitute values given:


V = 
V = 

Complementary angles
Explanation:
Completely angles are two angles that equal 90°
This is a perfect example of that
