V=πr^2h<br> solve for r<br> r=
egoroff_w [7]
To solve for r, you just need to isolate r. To do that, divide by h and π on both sides:
\frac{V}{h \pi }=r^2

Then, square root both sides to get rid of the 'squared':
r =  \sqrt{ \frac{V}{h \pi } }

Or, if you wanted the answer in terms of π, then just don't divide by it, just divide by h and then square root it.

Answer:

Scale\ Factor = \frac{1}{2}

ABC dilated

Step-by-step explanation:

Given

Triangles ABC and DEF

Required

Determine the scale of dilation

First, we pick a side on ABC

AB = 6

Pick a corresponding side on DEF

DE = 3

The scale factor is then calculated as:

Scale\ Factor = \frac{DE}{AB}

Scale\ Factor = \frac{1}{2}

i.e. ABC was dilated by 1/2

HELP PLSSS ASAP!!!!!!!!
neonofarm [45]

Answer:

x = 5.5

Step-by-step explanation:

PM = MR

4x - 12 = -2x + 21         {add 2x to both the sides}

4x - 12 + 2x = -2x + 2x + 21

6x - 12 = 21         {Add 12 to both sides}

6x - 12 + 12 = 21 + 12

            6x  = 33

              x = 33/6

x = 5.5
