If the volume of the cone is 120 cm", what is the volume of the cylinder?

Answer:

let the two complementary angles be x and 90-x

x= 7t (say)

90-x= 11t

x+90-x=90= 7t+11t=18t

90=18t

t=90/18= 10/2= 5

so x= 7×5=35 degrees

and 90-×=90-35=55 degrees

Answer:

Step-by-step explanation:

Say thanks

mark brainlist

and rate 5!

x= 7t (say)

90-x= 11t

x+90-x=90= 7t+11t=18t

90=18t

t=90/18= 10/2= 5

so x= 7×5=35 degrees

and 90-×=90-35=55 degrees

Step-by-step explanation:

cos62˚ ≈ 0.469

0.469 x 12 = 5.628

The value of cos62 x 12 is 5.634.

We are given that;

The trigonometric function

cos62 x 12

Now,

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

To find the value of cos62 x 12, we can use a calculator or a trigonometric table.

we get:

cos62 x 12 = 0.4695 x 12

= 5.634

Therefore, by trigonometric function the answer will be 5.634 (approx.)

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

Thus,

[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]

Let us take X = 6 , Then Y = 13-6 = 6

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

Answer:

m<1 = m<2 = 98

Step-by-step explanation:

the measurement of angle 1 and 2 are the same because the two triangle half's (top and bottom) of the polygon are congruent.

any 4 sided polygon has sums of their internal angles = 360 degrees.

(for example a square has four 90 degrees angles, 360=90+90+90+90)

we know that 2 angles are 90 and 74,

we also know that the 2 other angles (m<1 and m<2) are the same,

m<1 +m<2 +90 +74=360

m<1+m<2=360-90-74

2*m<1=196

m<1=196/2

m<1=98

m<2=98

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.

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
