If r = 9 units and h = 6 units, what is the volume of the cylinder shown above?
Use 3.14 for .
A.
593.46 cubic units
B.
2,289.06 cubic units
C.
1,526.04 cubic units
D.
847.8 cubic units

C. 1526.04 cubic units

Step-by-step explanation:

So we look at what we are given, here we see that the radius is 9 units and the height is 6 units. We then plug these into the volume of a cylinder equation.

V=h×πr²

V=6×π×9²

V=6×π×81

V=486×3.14

V=1526.04 cubic units

Therefore the volume is 1526.04 cubic units.

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
