Answer:

384π cm³

Step-by-step explanation:

Formula for the volume of a cone is $\displaystyle \large{\frac{1}{3}\pi r^2 h}$ where:—

r is radius
h is height

Our radius is given in an attachment which is 12 cm and height is 8 cm. Substitute these values in the formula:—

$\displaystyle \large{V = \frac{1}{3}\pi (12)^2 \cdot 8}\\\displaystyle \large{V = \frac{1}{3}\pi \cdot 144 \cdot 8}\\\displaystyle \large{V = 48 \pi \cdot 8}\\\displaystyle \large{V = 384 \pi}$

__________________________________________________________

Summary

Volume (Cone)

$\displaystyle \large{V = \frac{1}{3}\pi r^2 h}$ where:—

h is height or perpendicular.

r is radius.

Value of Pi (Commonly Used)

$\displaystyle \large{\pi \approx 3.14}$

Rectangle QRST has vertices located at Q(-9, -3), R(-1,-1), S(0,-5) and T(-8, -7). What is the length of side ST?

yaroslaw [1]

Answer:

$\huge\boxed{\sf |ST| = 8.2 \ units}$

Step-by-step explanation:

S = (x1,y1) = (0,-5)

T = (x2,y2) = (-8,-7)

Using distance formula to find the length of ST.

$|ST|= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\|ST| = \sqrt{(-8-0)^2+(-7-(-5))^2} \\\\|ST| = \sqrt{(-8)^2+(-7+5)^2} \\\\|ST| = \sqrt{64+(2)^2}\\\\|ST| = \sqrt{64+4} \\\\|ST| = \sqrt{68} \\\\|ST| = 8.2 \ units\\\\\rule[225]{225}{2}$

Hello can you please help me posted picture of question

leva [86]

P (Not a 2) = P(2) + P(3) + P(4)

P(1) = 0.30
P(3) = 0.15
P(4) = 0.15

So,

P( Not a 2) = 0.30 + 0.15 + .15 = 0.60

So, the answer to this question is option D
