The volume of the cylinder ≅ 197.82[tex]cm^{2}[/tex]

Step-by-step explanation:

The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:

V = π[tex]r^{2}[/tex][tex]h[/tex]

(now substitute the values of "r" and "h", and get...)

V = π[tex]r^{2}[/tex][tex]h[/tex]

[tex]V = (3^{2} )(7)[/tex] x π

V = (9)(7)π

V = 63π

V ≅ 197.82[tex]cm^{2}[/tex]

Answer:

x= 70°, y=40°

Step-by-step explanation:

2x=140

x= 70

y= 180-140= 40

140 + y = 180

y = 180 - 140

y = 40

2x + 40 = 180 (Angle Sum Property)

2x = 180 - 40

2x = 140

x = 140/2

x = 70

X = 70

Y = 40

Answer:

Y < 2X

Step-by-step explanation:

Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"

It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted

Thus, [tex]Y < 2X[/tex]

[tex]X + Y = 12[/tex] acres

[tex]Y = 12-X[/tex] acres

[tex]3 {w}^{2} + 10w + 8[/tex]

Step-by-step explanation:

Let The width as (w) and lenth as(l)

Then l=3w

When the width increase by 2

Then the New width is w+2

And the lenth increase by 4

Then the New lenth is 3w+4

Then we can find the area

Answer:

400 m^2.

Step-by-step explanation:

The largest  area is obtained where the enclosure is a square.

I think that's the right answer because a square is a special form of a rectangle.

So the square would be 20 * 20  = 400 m^2.

Proof:

Let the  sides of the rectangle be x and y m long

The area A = xy.

Also the perimeter  2x + 2y = 80

x + y = 40

y = 40 - x.

So substituting for y in A = xy:-

A = x(40 - x)

A = 40x - x^2

For maximum value of A  we find the derivative and equate it to 0:

derivative A' =  40 - 2x = 0

2x = 40

x = 20.

So y = 40 - x

= 40 - 20

=20  

x and y are the same value so x = y.

Therefore for maximum area the rectangle is a square.

The largest area of rectangle will be 400 square meters.

Let us consider the length and breadth of rectangle is x and y respectively.

Perimeter of rectangle is given that 80 meters.

                                  [tex]2x+2y=80\\\\x+y=40\\\\y=40-x[/tex]

 Area of rectangle is,

                                        [tex]=x*y\\\\=x*(40-x)\\\\A=40x-x^{2}[/tex]

  For maximum area, differentiate Area with respect to x  and equate with zero.

                           [tex]\frac{dA}{dx} =\frac{d}{dx}(40x-x^{2} ) \\\\\frac{dA}{dx} =40-2x=0\\\\x=40/2=20m[/tex]

       So,    [tex]y=40-20=20m[/tex]

Area  = [tex]20*20=400m^{2}[/tex]

Thus, The largest area of rectangle will be 400 square meters.

Answer:

1. 24/40, 32/40, 24/32 (This is in order from top to bottom)

2. 21.1

3. 4.1

Step-by-step explanation:

1. Here, we only have to focus on Angle X.

Let's label in the sides:

Opposite = YZ = 24

Adjacent = XY = 32

Hypotenuse = XZ = 40

SOHCAHTOA simply means:  You can memorise this through the acrostic poem of - Slap On Head Causes A Headache Take One Aspirin, but I remember it by Suck A Toe because that's what it sounds like.

Sin(x) = Opposite/Hypotenuse

Cos(x) = Adjacent/Hypotenuse

Tan(x) = Opposite/Adjacent

Sin(X) = 24/40

Cos(X) = 32/40

Tan(X) = 24/32

The question only asks to give the ratios by using / for a fraction, so we don't simplify it.

2. We are given the angle of 64°, the opposite length 19 and we have to work out x, which is the hypotenuse. We can use the sin function as we have our opposite length and we have to work out the hypotenuse.

Sin(64) = 19/x

xSin(64) = 19

x = 19/Sin(64)

x = 21.13943687

x = 21.1

3. We are given the angle of 70°, the hypotenuse 12 and we have to work out x, which is the adjacent side. We can use the cos function as we have to work out the adjacent side and we have our hypotenuse given to us.

Cos(70) = x/12

12Cos(70) = x  All we have to do here is multiply by 12!

x = 4.10424172

x = 4.1
