Step One
Find the radius of the cone. 
d = 6 which is given.
r = d/2
r = 6/2
r = 3

Remark
That's one of the sides of a right triangle. The other side is the slant of 9 inches. This is the hypotenuse.

Step Two
Find the height
h = ??
r = 3
Slant = 9

Use the Pythagorean theorem.

h^2 + r^2 = s^2
h^2 + 3^2 = 9^2
h^2 + 9 = 81  subtract 9 from both sides.
h^2 = 81 - 9
h^2 = 72
h = sqrt(72)

Step three
Express the answer
h = sqrt(72)
h = 8.49   <<<<<< Answer, but see below.

If you need this as a square root, then factor 72
72 = 6*6*2

h = sqrt(6* 6 * 2) The rule for square roots is if you have 2 of them you can take one outside the square root sign and throw the other one away.

h = 6 * sqrt(2) <<<< Answer

The square root of 73. Since the theorem is a^2+b^2=c^2 and only works with right triangles. You take 2/2 the base so you have a right triangles with a hypotenuse if 9 and a side of 3. Then you just plug in to solve.

The answer is 11/36

2/12 chance of rolling fours

because there are 2 sides containing a four on both dice combined and 12 sides in total.

Doubles mean you have to roll the same number simultaneously so let’s say we want to calculate the probability for double ones: then it’s 1/6 on the first dice for a one, and 1/6 on the second dice to land on a one as well.

I personally like to imagine a box like this:
_ _ _ _ _ _

If you have one dice then it’s just a random segment on one of the lines. If you want the specific result from two dice then you want two specific segments which is also the 1 specific tile out of 36 (6 width times 6 height). So you multiply.

1/6 * 1/6 = 1/36 chance to roll double of ones

And 1/36 chance to roll double twos, threes, fours, fives, and sixes. But we don’t count the double fours because any four will do. So:

1/36 * 5 = 5/36

So for the probability of either doubles or containing a four is the probability of doubles of either number plus the probability of either dice being a four:

5/36 + 2/12 =

5/36 + 6/36 =

11/36

Can someone help me?
mestny [16]

Answer:

Step-by-step explanation:

To do this, we must use the unit circle. At the angle \frac{\pi }{6} the coordinate pair is (\frac{\sqrt{3} }{2}, \frac{1}{2}) and the hypotenuse is 1

Now that we know these we can start using the trig functions

sin = y

cos = x

tan = \frac{y}{x}

And the other functions would be the reciprocal of these

csc = \frac{1}{y}

sec = \frac{1}{x}

cot = \frac{x}{y}

This would mean that

sinx = \frac{1}{2}

cosx =\frac{\sqrt{3} }{2}

tanx =\frac{1}{\sqrt{3} } or \frac{\sqrt{3} }{3} if you're supposed to rationalize your denominators

cscx = 2

secx = \frac{2}{\sqrt{3} } or \frac{2\sqrt{3} }{3}

cot = \sqrt{3}
