For this case we have that by definition, the volume of a cone is given by:
Where:
r: It is the radius of the cone
h: It is the height of the cone
According to the statement data we have:
Substituting in the formula:
We cleared the radius:
We choose the positive value:
We round and we have that the radius of the cone is:
ANswer:
Y=-1/3x-1 I believe is the correct answer
78/3 is 26 to get the number see how many times does 3 enter to 7 it goes 2 times becuase of 3,6, and you have a reminder of one. drag the one in the bottom and pull down the 8 to get 18 and 18/3=6. put the six above and you have 26 as your answer.<span />
You would divide both sides by 6 so that the co efficient of the unknown number is equal to 1. Which makes 6m into 1m and 24 into 4. Which means m has to equal to 4
Answers:
- h = sqrt(55) centimeters
- area = 3*sqrt(55) square cm
Your teacher may want the numbers only, so you may have to leave off the units.
We have these approximations:
sqrt(55) = 7.416198
3*sqrt(55) = 22.248595

Explanation:
ABC is isosceles, meaning that the altitude (aka height) h cuts side BC into two equal pieces. BC = 6 cuts in half to 3.
Let's say point D is on BC and at the base of the altitude. In other words, D is at the midpoint. Triangle ABC is cut into two smaller triangles ABD and ADC.
Let's focus on triangle ADC, which is a right triangle. It has a horizontal side of DC = 3 and vertical side AD = h. The hypotenuse is AC = 8.
---------
Let
Apply the pythagorean theorem
a^2 + b^2 = c^2
h^2 + 3^2 = 8^2
h^2 + 9 = 64
h^2 = 64-9
h^2 = 55
h = sqrt(55) ..... exact
h = 7.416198 ..... approximate
---------
Once we determine the height of triangle ABC, we can compute the area
base = BC = 6 cm
height = AD = h = sqrt(55) cm
area = 0.5*base*height
area = 0.5*6*sqrt(55)
area = 3*sqrt(55) .... exact
area = 22.248595 .... approximate
The units for the area are "square cm" or "cm^2".
