Solve for m.<br> 2= m/2 -7<br> M=
crimeas [40]

Answer:

m=18

Step-by-step explanation:

First add 7 to both sides.

2+7=m/2

Simplify 2+7 to 9

9=m/2

Multiply both sides by 2

9*2=m

Simplify 9*2 = 18

18=m

Guyss please help me with this question. I tried a thousand times but it's still incorrect.
Shalnov [3]

Answer: 17.68cm

Step-by-step explanation:

Using the area formula of a cone, find the height first.

A=\pi r(r+\sqrt{h^2+r^2})

Solve for h,

Begin by dividing by \pi r

\frac{A}{\pi r}=r+\sqrt{h^2+r^2}

Subtract r.

\frac{A}{\pi r}-r=\sqrt{h^2+r^2}

Square both sides.

(\frac{A}{\pi r}-r)^2=(\sqrt{h^2+r^2})^2

(\frac{A}{\pi r}-r)^2=h^2+r^2

Subtract r^2

(\frac{A}{\pi r}-r)^2-r^2=h^2

Extract the square root.

\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =\sqrt{h^2}

\sqrt{(\frac{A}{\pi r}-r)^2-r^2 } =h

Plug in your values.

\sqrt{[\frac{670cm^2}{(3.14)(8cm)}-(8cm)]^2-(8cm)^2 } =h

Solve;

\sqrt{[\frac{670cm^2}{25.12cm}-(8cm)]^2-(8cm)^2 } =h

\sqrt{[26.67cm-(8cm)]^2-(8cm)^2 } =h

\sqrt{(18.67cm)^2-(8cm)^2 } =h

\sqrt{348.57cm^2-64cm^2}=h

\sqrt{284.57cm^2}=h

15.77cm=h

------------------------------------------------------------------

Now, to find the slant height use this formula: l=\sqrt{h^2+r^2}

l=\sqrt{(15.77cm)^2+(8cm)^2}\\l=\sqrt{248.69cm^2+64cm^2}\\ l=\sqrt{312.69cm^2}\\ l=17.68cm
