Find the volume of a pyramid with a square base, where the side length of the base is 18.2\text{ in}18.2 in and the height of the pyramid is 28.8\text{ in}28.8 in. Round your answer to the nearest tenth of a cubic inch.

The volume is 3179.9 in³

Step-by-step explanation:

Data

side length of the base, a = 18.2 in

height of the pyramid, h = 28.8 in

Square pyramid volume is computed as follows:

V = a² * h/3

Replacing with data, we get:

V = 18.2² * 28.8/3

V = 3179.9 in³

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2

answer: 72: 111
