Which expression represents the volume of the cone, in
cubic units?
Piex2
2piex3
o 1/3piex?
o 1/12piex
Answer:
For this case we know that the diameter and height of a cone are both equal. That means:
With with r the radius. The volume of a cone is given by:
And for this case we know that h =x and so then
And replacing we got:
And the best option would be:
1/12pix^3

Answer: x = 15
we have: (6x - 5)° + (6x + 5)° = 180°
⇔ 12x = 180
⇔ x = 180/12=15

Answer:
0.4 - 0.40 - 4/10 -

Answer:
No unless x is being used to define only elements of an integer set.
Step-by-step explanation:
No, not in general unless x is defined as a integer or a subset of the integers like the naturals, whole numbers....
Usually 6<=x<=10 means all real numbers between 6 and 10, inclusive. This means example that 6.6 or 2pi are in this set with infinitely other numbers that I can't name.
{6,7,8,9,10} just means the set containing the numbers 6,7,8,9,10 and that's only those 5 numbers.
Answer:
14.
15.
Step-by-step explanation:
Solving (14):
First, we solve for x.
Since sides , then
This is so because the theorem of ASA (Angle-Side-Angle)
So, we have:
Collect Like Terms
Divide both sides by 3
Solving for m<B, m<C and m<D.
We simply substitute 11 for x in their respective expressions.
Solving (15):
First, we solve for x.
Since , then
This is so because the theorem of SAS (Side-Angle-Side)
So, we have:
Collect Like Terms
Divide both sides by 2
Solving for WX, WY and XY
We simply substitute 4 for x in their respective expressions.
