What is the volume of a cylinder, in cubic centimeters, with a height of 2 centimeters

Mathematics
1 answer:
harina [27]3 years ago
7 0

Answer:

<h2>         V ≈ 628.3 cm³</h2>

Step-by-step explanation:

Volume of cylinder:  V = π×r² × h

diameter = 20 cm  ⇒  r = 10 cm

h = 2 cm

Volume:

V = π×(10)²×2 = 200π cm³ = 628.318.... cm³ ≈ 628.3 cm³

Solve for x given two sides

Solution

x is an angle hence we are gonna use the formula Sin

Sin 0 = opp/hyp

0 represents theta.


Sin 0 = opp/hyp
Sin 0 = 27/33

Put 27/33 in decimal form

= 0.8181

Transpose to make 0 the subject


Sin 0 = 0.8181

0 = Sin-1 0.8181

When adding Sin from one side to another it becomes Sin inverse.

0 = Sin-1 08181

Now we find the answer

0 = Sin-1 0.8181

= 54.89 degrees

Therefore x is equal to 54.9 to the nearest tenth.

Work out the area of a circle with a radius 6.2cm, take n/pi to be 3.142 and give your answer to 2 decimal places.
s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Area is pi times r squared.  I don't know how to write that on the keyboard.  Take your pi(3.142) times the radius(6.2)squared.  Pemdas tell us to do exponents first, so 6.2 squared is 38.44.  To square a number, just multiply it times itself.  So now, we have pi(3.142) times the squared radius(38.44).  So, 3.142X38.44=

120.778  Second place is seven followed by eight.  Round up.  120.78

Please help!!!
Leto [7]

Answer:

 - The scientist can use these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

- The scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse} and solve for the distance between the Sun and the shooting star (which would be the hypotenuse of the righ triangle).

Step-by-step explanation:

 You can observe in the figure attached that  "AC" is the distance between the Sun and the shooting star.

Knowing the distance between the Earth and the Sun "y" and the angle x°,  the scientist can use only these two measurements to calculate the distance between the Sun and the shooting star by applying one of the trigonometric functions: Cosine of an angle.

 This is:

cos\alpha=\frac{adjacent}{hypotenuse}

In this case:

\alpha=x\°\\\\adjacent=BC=y\\\\hypotenuse=AC

Therefore, the scientist can substitute these measurements into cos\alpha=\frac{adjacent}{hypotenuse} , and solve for the distance between the Sun and the shooting star "AC":

cos(x\°)=\frac{y}{AC}

AC=\frac{y}{cos(x\°)}

How do you solve this equation<br> 5(8x-2)=270
raketka [301]
5(8x-2)=270
distribute the 5 into 8x-2
5*8x-5*2=270
you get
40x-10=270
combine like terms
40x=280
divide both sides by 40 to find x
x=7

£150 is divided between Malachy, Paul &amp; Brian so that Malachy gets twice as much as Paul, and Paul gets three times as much
Dmitry_Shevchenko [17]

Answer:

£90

Step-by-step explanation:

Let M = Malachy's share

and P = Paul's share

and B = Brian's share.

We have three conditions:

                                              (1)               M = 2P

                                               (2)                P = 3B

                                               (3)   M + P + B = 150

Solve for B:

Substitute (2) into (3)             (4) M + 3B + B = 150

                                               (5)       M + 4B = 150

Substitute (2) into (1)                                  M = 2(3B)

                                               (6)                M = 6B

Substitute (6) into (5)                6B + 3B + B = 1 50

                                               (7)                B = 15

Solve for P:

Substitute (7) into (2)                                  P = 3×15

                                               (8)                P = 45

Solve for M:

Substitute (8) into (1)                                  M = 2×45

                                                                   M = 90

Malachy gets £90.
