Answer:
Step-by-step explanation:
The anwser is you divide the numbers the mutiply the 100000 times
V = π R^2 H/3
V = π (4.5)^2 8.3/3
V = π (20.25) 2.76666667
V = 176.01
4x² - 3xy + 9y² - 3(5xy + 7y²)
4x² - 3xy + 9y² - 3(5xy) - 3(7y²)
4x² - 3xy + 9y² - 15xy - 21y²
4x² - 3xy - 15xy + 9y² - 21y²
4x² - 18xy - 12y²
