The volume of the cone with a radius of 3 cm and height of 8 cm is 24 π cm³. Then the correct option is D.

<h3>What is Geometry?</h3>

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

Consider this composite figure made of a cone and a cylinder.

A cone has a height of 8 centimeters and a radius of 3 centimeters.

A cylinder has a height of 7 centimeters and a radius of 3 centimeters.

Then the volume of the cone will be

We know that the volume of the cone

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

Then we have

\rm Volume  =  \dfrac{1}{3} \ \pi \ 3^2 *8\\\\\rm Volume  =  \dfrac{1}{3} \ \pi *9*7\\\\\rm Volume  =  \dfrac{1}{3} \ \pi \ 72\\\\Volume = 24 \ \pi

What is the approximate solution of the linear system represented by the graph below
VashaNatasha [74]
ANSWER

The approximate solution is

(4, - 1)

EXPLANATION

The point of intersection of the two lines is the solution of the linear systems represented by the graph.


From the graph we can determine that each box is 2 units.


From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be
(4, - 1)


Note that since each box is two units, half way between the boxes gives one unit.

Galileo wanted to release a wooden ball and an iron ball from a height of 100 meters and measure the duration of their fall. He
ICE Princess25 [194]
For this case what you have is the same as a rectangle triangle where you have as data the degree of inclination of the hypotenuse with respect to the base and the height of the triangle.
 We have to find the value of the hypotenuse.
 For this we use the following trigonometric relationship:
 senx = C.O / h
 Where
 x: angle
 C.O: opposite leg
 h: hypotenuse.
 Substituting the values we have:
 sen (12) = 100 / h
 We cleared h:
 h = 100 / sin (12)
 h = 480.97 m
 Answer: 
 Galileo should walk 480.97 m up the inclined plane
