First, find the scale factor.
8.4 / 7 = 1.2
9 / 7.5 = 1.2
7.2 / 6 = 1.2
Since both solids are different sizes, the solids aren't congruent.
The size ratio for all the sides are:
8.4:7
9:7.5
7.2:6
Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.
Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.
Best of Luck!
Answer: The total cost will be $156.85.
Step-by-step explanation:
Since we have given that
Time taken by labor to assemble the each skateboard is given by

Time taken by labor to finish and stain each skateboard is given by

Cost of labour to the company per hour = $36.00
According to question,
We will use "Distributive Property":


Hence, the total cost will be $156.85.
Cylinder area=height times area of base (area of base=area of circle)
height =1.8
radius=6.1
area of circle=pi times r^2
area of circle=pi times 6.1^2=37.21π
times height
1.8 times 37.21π=66.978π
volume=66.978π ft^3
