A model of a volcano has a height of 12 in. , and a diameter of 12 in. What is the approximate volume of the model? Use 3. 14 to
jenyasd209 [6]

The approximate volume of the model will be

v=452.33 inch^{2}

<h3 /><h3>What is the approximate volume of the model? </h3>

It is given that

Height of the volcano =12 inch

Diameter of the volcano= 12inch=r=6inch

So the volume of the model will be =

=\dfrac{1}{3\\} \pi \times r^{2} \times h

= \dfrac{1}{3} \pi \times (6)^{2} \times 12

v=452.33inch^{2}

Thus the approximate volume of the model will be  v=452.33 inch^{2}

A bag contains five white marbles and five black marbles. What is the probability of drawing a white marble, not replacing it, a
Lelu [443]

~ ANSWER=1/2 ~

Simple probability is found by counting all the results which fit requirements and dividing by all possible results.

To find probability of two results in a row, multiply chance of first result by chance of second result.

Since you are replacing the marble before the second draw, we don’t have to figure out the various changes in odds for the different possible first draws. It’s just that simple.

There are 5 white marbles

There are 4 red marbles

There are always 20 marbles in all

5/20*4/20=1/4*1/5=1/20 or 1/2

By coincidence, the same as the chance of drawing the white marble in one draw.

Vinvika [58]

The number of small tiles are needed​ is 300 tiles.

<h3>Number of tiles needed</h3>

Using area of rectangular formula

Area of the room = length(l) × breadth (b)

Area of the room=300 cm×180 cm

Area of the room=54,000 cm²

Number of tiles needed = Area of rectangular region / Area of one tile

Number of tiles needed=54,000/180

Number of tiles needed=300 tiles

Therefore the number of small tiles are needed​ is 300 tiles.
