In this question, the volume of the cone is needed. The equation used to determine the volume of the cone is (1/3)π(r²)h
To solve for the volume, 
V = (1/3)π(3²)(10)
   = (1/3)(9)(10)π
   = (3)(10)π
   = 30π cm³
The correct answer is the first option which is 30π cm³.

Answer: A. 30π cm3

Step-by-step explanation:

The equation for cones

V = (1/3) π * r² * h

Plug in the numbers r = radius which is half of the diameter and h = height. Also leave out π because of the answer choices.

so... (1/3) * 3² * 10 = 30

30π

What is the intersection of the given lines AE and DE?
cricket20 [7]

Given statement is "What is the intersection of the given lines AE and DE?".

That gives us information that there are two lines named AE and DE which intersect each other. Now we have to find their intersection point.


If you see carefully the name of both lines AE and DE then you will find that; they have common letter "E" in their name.

That means point "E" lies on both lines.

We know that intersection point always lies on both lines.

Which proves that point "E" is the intersection point.


Hence choice "<u>B. Point E" </u>is the final answer.
