A frustum is formed when a plane parallel to a cone’s base cuts off the upper portion as shown.

A cone is shown. The top of the cone is cut off to form a frustum of the bottom portion. The smaller cone formed has a radius of 1.5 and a height of 6.4. The frustum has a radius of 3 and a height of 6.8.

What is the volume of the frustum? Express the answer in terms of π.

15.6π units3
20.4π units3
34.8π units3

Step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:
