Answer:
86.9 cm^3
Step-by-step explanation:
You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.
2(5.3x2)=21.2
2(4.5x2)=18
2(4.5x5.3)=47.7
You then add the values together...
21.2+18+47.7=86.9
Answer: The polynomial 3x^2 is a monomial with a degree of 2.
The polynomial x^2y + 3xy^2 + 1 is a trinomial with a degree of 3.
This problem is currently unsolvable as we do not know if the semi-circle has a radius of 31 or 19.
