What’s the volume of a cylinder with a radius of 6ft and height of 14ft? pls show work

Daniel [21]

Answer:

Given -

radius of cylinder = 6 ft
height of cylinder = 14 ft

Now ,

$volume = \pi \: r {}^{2} h \\ = > \frac{22}{\cancel{7}} \times 6 \times\cancel{ 14} \\ \\ = > 22 \times 6 \times 2 \\ = > 264 \: ft {}^{3}$

hope helpful~

A polygon has n sides. Two of its sides are right angle while the remaining each side is 144.find n

deff fn [24]

Use the formula that states that the sum of the angles of an n-sided polygon is given by
S=(n−2)180
0
........(1)

Since we are given that the two angles are right angles and each of the remaining angles is 144
0
, therefore, the sum is:

S=90
0
+90
0
+(n−2)144
0
.........(2)

Therefore setting (2) equal to (1) we get

(n−2)180
0
=90
0
+90
0
+(n−2)144
0

⇒(n−2)180
0
−(n−2)144
0
=180
0

⇒(n−2)(180
0
−144
0
)=180
0

⇒(n−2)(36
0
)=180
0

⇒n−2=
36
180

⇒n−2=5
⇒n=5+2=7

Hence, the polygon has 7 sides.

We looking for distance

drek231 [11]

Answer:

240 m

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min. The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid. The area of a trapezoid is $A=\frac{1}{2}h(b_1+b_2)$ where the b's are the lengths of the two parallel base and h is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

$A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}$
