Answer:
The answer is 42.67 cubic inches.
Step-by-step explanation:
Both the models are in the shape of a square pyramid.
The length of the sides of the base for both the models is 8 inches.
Amy’s model is 5 inches tall and Alex’s model is 3 inches tall.
The volume is given by :
So, Amy's figure volume is :
= 106.67 cubic inches
And Alex's figure volume is:
= 64 cubic inches
So, the difference between volumes is = cubic inches.
The answer is 42.67 cubic inches.

Answer:
Here's what I get.
Step-by-step explanation:
9. (6, -8)
The reference angle θ is in the fourth quadrant.
∆AOB is a right triangle.
OB² = OA² + AB² = 6² + (-8)² = 36 + 64 = 100
OB = √100 = 10
10. cot θ = -(√3)/2
The reference angle θ is in the second quadrant.
∆AOB is a right triangle.
OB² = OA² + AB² = (-√3)² + (2)² = 3 + 4 = 7
OB = √7
