Answer:

2.0 inches

Step-by-step explanation:

Volume of a cone is given by

V=\frac {\pi r^{2}h}{3}

Making h the subject of the formula, the formula then

h=\frac{3V} {\pi r^{2}}

Substituating 301.4 in³ for V and 12 in for r then

h=\frac{3*301.4} {\pi 12^{2}}=1.9987208269957in\\h\approx 2 in

Therefore, h is 2.0 inches

KATRIN_1 [288]

Answer:

0.083

Step-by-step explanation:

Numbers of Cube = 6

Faces on coins = 2

Therefore, The total outcomes = 6 \times 2 = 12

Now the favourable outcome that he rolls a 4 & flips a head = 1

The probability that he rolls a 4 & flips a head = 1

\frac{Favourable \: Outcome}{Total \: Outcome}

=> The probability that he rolls a 4 & flips a head = \frac{1}{2}  = 0.83333/ approx. 0.83

Therefore, The probability that he rolls a 4 & flips a head = 0.083

Find the value of x
AfilCa [17]
The answer is X = 12.
This is how to get that answer: the formula for the intersecting secant and tangent outside the circle is a^2 = b(b+c) If you use the numbers in the pic you will get x^2 = 9(9+7) so the number after the equal sign will be 144, so x^2 = 144. To undo the square youre gonna use the square root on both sides, so you have X = 12.
