A cylinder has a volume of 321 cubic units. If a cone has the same height and radius as the cylinder, what is the volume in cubic units?A.107 cubic units
B.214 cubic units
C.642 cubic units
D.963 cubic units

Answers

The volume of the cone which has the radius and height same as the cylinder of volume 321 cubic units is 107 cubic units.

What is the volume?

A cylinder is defined as a surface made up of all the points on all the parallel lines that pass through a set plane curve in a plane that is not parallel to the provided line.

The volume of the cylinder is given by the formula,

$\text{Volume of cylinder} = \pi r^2 h$

$321 = \pi r^2 h$

Now, as it is given that the radius and the height of the cone are the same, therefore, the volume of the cone can be written as,

$\text{Volume of cone} = \frac13 \pi r^2 h$

As we know the value of πr²h, therefore, substitute the value,

$\rm\text{Volume of cone} = \frac13 * 321 = 107\ units^3$

Thus, the volume of the cone which has the radius and height same as the cylinder of volume 321 cubic units is 107 cubic units.

For #3:

y = 1/2x, x = -18

Plug in -18 for 'x':

y = 1/2(-18)

y = -9

For #4:

y = -4x + 6, x = 1

Plug in 1 for 'x':

y = -4(1) + 6

y = -4 + 6

y = 2

1. $(2,3),(6,4),(8,11),(10,4)$
2. $(7,-13),(9,-9),(11,-5),(14,-1)$
Both relations are functions.

3. $y(-18)=(1)/(2)\cdot(-18)=-9$
4. $y(1)=-4\cdot1+6=-4+6=2$

5. It's easy to notice it's a linear function.
$y=mx+b\nm=(y_2-y_1)/(x_2-x_1)\n\nm=(-10-(-5))/(2-1)\nm=(-5)/(1)\nm=-5\n\n-5=-5\cdot1+b\nb=0\n\n\boxed{y=-5x}$
