The volume of a cylinder is 32.25 cubic inches. If a cone has the same height and radius as the cylinder, what is its volume?

PtichkaEL [24]

The volume of a cylinder with a radius r and a height h:

$V_1=\pi r^2h$

The volume of a cone with a radius r and a height h:

$V_2=\dfrac{1}{3}\pi r^2h$

Therefore

$V_2=\dfrac{1}{3}V_1$

We have $V_1=32.25\ in^3$

Substitute:

$V_2=\dfrac{1}{3}\cdot32.25=10.75\ in^3$

Answer: The volume of a cone is equal 10.75 in³

v(x)=(s/t)
= (3x - 6) / (-3x+6)
= [3(x-2)] / [-3(x-2)] --> 3 is factored out
= 1/-1 ---> common terms are cancelled out.
= -1 ---> This is the simplified formula.

To find the domain, we equate the denominator to 0.
-3x+6 = 0
3x = 6
x = 2
Domain: all values except 2.

w(x)=(t/s)(x)
= (-3x+6)x / (3x-6)
= [-3x(x-2)] / [3(x-2)] --> 3 is factored out
= -x --> The common terms are cancelled out. This is the simplified formula.

Solving for domain:
3x-6 = 0
3x = 6
x = 2
Domain: all values except 2.
