Answer:
5
Step-by-step explanation:
-2x -9y = -25
-(-4x -9y =-23)
2x = -2
x = -1
-2(-1) -9y = -25
2 - 9y = -25
-9y = -25 -2
-9y = -27
y = 3
(-1,3)
Answer:
366.5cm³
Step-by-step explanation:
1. Determine the height and radius of cone.
2. Using the formula for the volume of a cone input where there is an h and r.
3.Where it says Area of base, it is talking about the circular base and that you need to find its area. (π×r²), you already have the radius so you put it in the formula and solve (π×5²)
4. Once you have the area of the base you can now completely solve. Multiply ⅓×(78.54)×14
