The surface area of a cone with radius r units and slant height s units is shown below:

1 answer:

3 0

Lateral Area = (π • r • slant height)
If radius = 2 and
slant height = 3 then


Lateral Area = (π * 2 * 3)

The lateral area = 18.8495559215

I have a flower vase with a 6 " diameter and is 12 " tall I want to fill it 2/3 of the way full how many cubic inches will I fil

RSB [31]

Answer:

$72\pi\ in^{3}$

Step-by-step explanation:

step 1

Calculate the volume of the cylinder (flower vase)

The volume is equal to

$V=\pi r^{2}h$

we have

$r=6/2=3\ in$ -----> the radius is half the diameter

$h=12\ in$

substitute the values

$V=\pi (3)^{2}(12)=108\pi\ in^{3}$ ------> exact value

step 2

Calculate 2/3 of the volume

$V=(2/3)108\pi=72\pi\ in^{3}$

Answer: 130

In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130

**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles
