The formula for calculating the volume of a cone is solve this formula for h
elixir [45]

Answer:

V =  \frac{1}{3} \pi {r}^{2} h \\

multiply either sides by 3:

3 \times V = ( \frac{1}{3} \pi {r}^{2} h) \times 3 \\  \\ 3V = \pi {r}^{2} h

divide either sides by πr² :

{ \boxed{ \boxed{h =  \frac{3V}{\pi {r}^{2} } }}} \\

WILL MARK BRAINLIST!!! PLS HELP QUICK!!
Alborosie

Answer:

12.

Square root = 37,

Step-by-step explanation:

40^2 = 1600

35^2 = 30 * 40 + 25 = 1225

So the requred square is between 35 and 40

38^2 = 1444

37^2 = 1369 - so its this one.

Required difference = 1381 - 1369 = 12.

Solve for x. Please:)
lutik1710 [3]

Answer:

  x = 3

Step-by-step explanation:

The smaller triangle and larger one are similar, so corresponding sides are proportional.

  8/4 = (8 +(x -1))/5

  10 = x +7 . . . . . . . . . multiply by 5 and simplify

  3 = x . . . . . . . . . subtract 7

__

<em>Alternate solution</em>

The short segments are also proportional:

  (x -1)/(5 -4) = 8/4

  x -1 = 2 . . . . simplify

  x = 3 . . . . . . add 1

You are 100m from the base of a tall building. If your feet are exactly 180m from the top of the building, how tall is the build
KatRina [158]

Answer:

the building would be 280 feet (judging on how this is worded.)

Step-by-step explanation:

you are already 100 meters from the base ( bottom) of the building so you add 180 as you are 180 ft from the top of the building. 100 + 180 is equal to 280.
