Answer:
2,799 square cm
Step-by-step explanation:
Volume of cone: (1/3)π(9^2)(40)=1,080π
Volume of cylinder: π(3^2)(21)=189π
1,080π - 189π = 891π = 2799.2 square cm
Well it shows what your looking for. For example, when you use a line graph you use it to show time and what happens to like lets say a ecosystem and what happens to it over time. That's just one of a lot of different ways to show and analyze patterns in life.
1. 2 (x + 3) = x - 4
2x + 6 = x- 4
2x - x = -4 - 6
x = -4 + -6 = -10.
x = 10
2. 4 (5x - 2) = 2 (9x + 3)
20x - 8 = 18x + 3
20x - 18x = 3 + 8
2x = 11
x = 11/2 = 5.5
x = 11/2 or 5.5
These are the Answers.
