Answer:
(4x - 3) (4x+ 5)
Step-by-step explanation:
The volume of air surrounding the cone and inside the cylinder will be the difference of the volume of cylinder and the cone.
So,
Volume of air = Volume of cylinder - Volume of cone
Thus, the volume of the air surrounding the cone and inside the cylinder will be 1055.04 cubic centimeter
Answer:
Solution given:
Let there be a point P(x, y) equidistant from
A(-3, 2) and B(0,4),
so PA = PB,
![\sqrt{(x+3)²+(y-2)²}=\sqrt{(x-0)²+(y-4)²}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x%2B3%29%C2%B2%2B%28y-2%29%C2%B2%7D%3D%5Csqrt%7B%28x-0%29%C2%B2%2B%28y-4%29%C2%B2%7D)
squaring both side
![(\sqrt{(x+3)²+(y-2)²})^{2}=(\sqrt{(x-0)²+(y-4)²})²](https://tex.z-dn.net/?f=%28%5Csqrt%7B%28x%2B3%29%C2%B2%2B%28y-2%29%C2%B2%7D%29%5E%7B2%7D%3D%28%5Csqrt%7B%28x-0%29%C2%B2%2B%28y-4%29%C2%B2%7D%29%C2%B2)
x²+6x+9+y²-4y+4=x²+y²-8y+16
x²+6x+y²-4y-x²-y²+8y=16-4-9
