Answer:

First choice:

         \large\boxed{\large\boxed{h=\frac{3V}{784\pi};21cm}}

Explanation:

<em><u>1. Formula for the volume of a cone</u></em><u> (given)</u>

<em><u /></em>

      V=\frac{1}{3} (28^2)\pi h

<em><u>2. Identify the inverse of this function</u></em>

Solve for h:

       3V=(28)^2\pi h\\ \\ \frac{3V}{(28)^2\pi}=h\\\\h=\frac{3V}{(28)^2\pi}\\\\h=\frac{3V}{784\pi}

<em><u>3. Find the height of the cone, if its volume is 5488πcm³</u></em>

Subsititue V with 5488π

          h=\frac{3(5488\pi cm^3)}{784\pi cm^2}\\\\h=21cm

Find the value of x.
nikklg [1K]

Answer:

x = 13

Step-by-step explanation:

Sum or interior angles of a triangle is 180,

6x + 19 + 5x - 15 + 3x - 6 = 180

6x + 5x + 3x + 19 - 15 - 6 = 180

14x + 19 - 21 = 180

14x - 2 = 180

14x = 180 + 2

14x = 182

x = 182 / 14

x = 13

A circular sector has a central angle of π6 radians and a radius of 9 ft.
ohaa [14]

Answer:

\approx \: 21.2 \:  {ft}^{2}

Step-by-step explanation:

central \:  \angle   =  \frac{\pi ^{c} }{6}  = 30 \degree \\  \\ area \: of \: the \: sector =  \frac{30 \degree}{360 \degree}  \times \pi {(9)}^{2}  \\  \\  =  \frac{1}{12}  \times 3.14 \times  81 \\  \\  =   \frac{1}{12}  \times 254.34 \\  \\  = 21.195 \:  {ft}^{2}  \\  \\  \approx \: 21.2 \:  {ft}^{2}
