Answer:

Step-by-step explanation:

<h2>Cone:</h2>

    diameter = 12 cm

                  r =  12 ÷ 2 = 6 cm

                 h = 6 cm

      \sf \boxed{\text{\bf Volume of cone = $\dfrac{1}{3} \pi r^2h$ }}

                                    \sf = \dfrac{1}{3}*3.14*6*6*6\\\\ = 226.08 \ cm^3

To find the surface area, we need to find the slant 'l'

       \sf l = \sqrt{h^2+r^2}\\\\       =\sqrt{6^2+6^2}\\\\        = \sqrt{36+36}\\\\ =\sqrt{72}\\\\= 8.49 \ cm

       \sf \boxed{\text{\bf Total surface area of cone = $\pi r(r+l)$}}

                                                         = 3.14 * 6 * (6 + 8.49)

                                                        = 3.14 * 6 * 14.49

                                                        = 273 cm²

HELP PLEASE<br><br> Which graph represents the system of inequalities?
Assoli18 [71]

Answer:

The answer to your question is in the picture below

Step-by-step explanation:

y + 3/4x < 2

y+ 3/4x = 2

y = -3/4x +2

Interceptions     (0,2) and (8/3, 0) It's a dotted line and we are interested in the area below the line

y - 1 ≥ 2x

y - 1 = 2x

y = 2x + 1 Interception, it's not a dotted line with interceptions (0,1) and (-1/2, 0), we are interested in the area up the line.

Tamia watched 1 2 of a movie in the morning, and she watched some more at night. By the end of the day, she still had 1 3 of the
KonstantinChe [14]

Answer: Tamiya watched \dfrac16 of the movie at night.

Step-by-step explanation:

Let x = part of movie watched at night.

Given  : Tanya watched \dfrac12 of movie in the morning.

Part left to watch = \dfrac13

As per given, we have

\dfrac12+x+\dfrac13=1\\\\\Rightarrow\ x=1-\dfrac13-\dfrac12\\\\\Rightarrow\ x=\dfrac{6-2-3}{6}\\\\\Rightarrow\ x=\dfrac16

Hence, Tamiya watched \dfrac16 of the movie at night.
