Answer:
Sketch the following three graphs:
1) y = (x - 5)²
2) y = -(x - 5)²
3) y = x - 5
First two are parabolas with vertex at (5,0)
Third one is a line which intersects both the parabolas as (5,0)
Answer:
Volume of cone = 209.44 cm²
Curved surface area of cone = 188.57 cm
Step-by-step explanation:
Given:
Height h = 8 cm
Slant height l = 10 cm
Radius r = 6 cm
Find:
Volume of cone
Curved surface area of cone
Computation:
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)π(5)²(8)
Volume of cone = 209.44 cm²
Curved surface area of cone = πrl
Curved surface area of cone = π(6)(10)
Curved surface area of cone = 188.57 cm
