Answer:

5cm^{3}

Step-by-step explanation:

<h2> This problem bothers on the mensuration of solid shapes, cone an cylinder.</h2><h2></h2>

from the formula of cylinder and cone we can see that the volume of a cone is 3 times smaller than that of a cylinder

volume=\pi r^{2} h....................cylinder

volume= \frac{1}{3} \pi r^{2}h.................cone

assuming all units in (cm)

Given data.

Volume of cylinder  =  15cm^{3}

Diameter d=  2cm

Radius r =   \frac{d}{2}= \frac{2}{2} = 1cm

Height h=  ??

we know that the expression for the volume of a cylinder is

volume=\pi r^{2} h

we can substitute our given data to find the height h

15= 3.142*1^{2}*h\\15=  3.142h

divide both side by 3.142 we have

h= \frac{15}{3.142}\\ h= 4.77cm

We can now use this height4.77cm and radius 1cm to find the equivalent  volume of a cone.

the expression for the volume of a cone is

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

substituting our data into the expression  we have

volume= \frac{3.142*1^{2*} 4.77}{3} \\volume= \frac{15}{3} \\voulume = 5cm^{3} \\

Answer:

EF=20

Step-by-step explanation:

EF is midsegment of the triangle so the equation is

AB/2=EF

7x-2/2=2x+8

7x-2=4x+16

7x-4x=16+2

3x=18

x=18/3

x=6

EF=2×6+8

=12+8

=20
