A cylinder has a radius of 3 feet and a height of 7 feet. Which of the following can be used to calculate the volume of a cone t

kramer

Answer:

$(3.14)(3)(7)$

Step-by-step explanation:

we know that

The volume of the cone is equal to

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

we have that the radius and the height of the cone will be equal to the radius and the height of the cylinder

$r=3\ ft$

$h=7\ ft$

$\pi =3.14$

substitute the given values

$V=\frac{1}{3}(3.14)(3)^{2} (7)$

$V=\frac{1}{3}(3.14)(9)(7)$

Simplify

$V=(3.14)(3)(7)$

Please help and show work

Step-by-step explanation:

Since PT = 2PM and AR = 2AD,

The midsegment MD must be the average of PA and TR:

Therefore we have

2(20x + 4) = 10 + (34x + 16)

=> 40x + 8 = 34x + 26

=> 6x = 18

=> x = 3

Hence length of MD

= 40(3) + 8 = 128.

What is the value x in the equation -2/5x-2=18? -50 -40 -8 -6

Usimov [2.4K]

-2x/5-2=18
-2x/5-2+2=18+2
-2x/5=20
-2x/5x5=20x5
-2x=100
-2x/-2=100/-2
x=-50
