Answer:

Diameter = 8

Step-by-step explanation:

Cone volume formula = (pi)*r^2*h/3

V = (12pi)*r^2*(9/3)

V = (12pi)*r^2*3

12/3 = 4

V =(pi)*4^2*h/3

4*2 = 8

The Diameter is 8

Answer:

2.2568m

Step-by-step explanation:

volume= 12 π cm³

or, 1/3 πr²h = 12π cm³

or, πr² × 9 = 12π ×3

or, r²= 36π/9π

or, r²= 4

or, r= 2

d = 2r = 2× 2= 4 cm

Kazeer [188]

To Euclid, a postulate is something that is so obvious it may be accepted without proof.

A. A straightedge and compass can be used to create any figure.

That's not Euclid, that's just goofy.

B. A straight line segment can be drawn between any two points.

That's Euclid's first postulate.

C. Any straight line segment can be extended indefinitely.

That's Euclid's second postulate.

D. The angles of a triangle always add up to 180.

That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."

How do you know if a given relation is a function or not a function?
lisov135 [29]

Answer:

In general, a relationship f (x) = y is a function only if, for each value of x that you plug into it, you get only one value for y.

Step-by-step explanation:

Sometimes the only way to tell if a given relationship is a function or not is to try various values for x to see if they yield unique values for y.

The ratios in an equivalent ratio table are 3:12, 4:16, and 5:20. If the first number in the ratio is 10, what is the second num
nekit [7.7K]

Answer:

I believe the answer would be 10/40. First, I simplified all of the given rations. You do this by finding the two numbers greatest common factor. For example, 3/12, 3 goes into 3 once and 3 goes into 12 four times. So that ratio would be 1/4. If you continue the pattern you would get 1/4 for all of them. Therefore, 10/40 would be correct since it's ratio would also be 1/4.
