Answer:
1. D. .
2. D. .
Step-by-step explanation:
1.
, where,
r = Radius of the cone,
h = Height of the cone.
Upon substituting our given values we will get,
Therefore, the volume of our given oblique cone is and option D is the correct choice.
2.
, where,
r = Radius of the cone,
h = Height of the cone.
Upon substituting our given values we will get,
Therefore, the volume of our given right cone is and option D is the correct choice.
The problem is really asking 5/6 divides by 1/6. This yields 5. Hope this helps!<span />
Answer: x=6 and y = -4 and x= -1 and y=3
Step-by-step explanation:
Your two equations are y = -x + 2
and y=x^2 -6x + 8
Subsituting y=-x+2, we get
-x + 2 = x^2 -6x + 8
x^2 -5x +6 = 0
Solving by the quadratic formula gives,
(5+/- sqrt(25+24))/2
Thus, the two solutions are 6, and -1.
So x=6
y= -4 and
x=-1
y= 3
(4/9)/(2/3)/(5/6)
