Answer:
5416.96ft^3
Step-by-step explanation:
First use the 4 as the height, and the 9.2 as the base to find just the big rectangle area using this formula:
1/2b*h: 1/2(9.2)*4=18.4
Then find the area of the little triangle:
1/2b*h: 1/2(4)*4=8
Then find the base of the triangle:
4*9.2=36.8
Lastly multiply all of those together to get the area
18.4*8*36.8=5416.96ft^3

option (2)
Using the cofunction identity
cosx = sin(90 - x) , then
cosb = sin(90 - b) = 0.75
2.85 x 10⁷
