Radius of cone ( r ) = 3 cm,

Curved surface area of a cone= 47.1 cm²

Curved surface area of a cone= πrl

47.1 = πrl

47.1 = 3.14 × 3 × l

l = 47.1 / (3.14 × 3)

l = 15.7 / 3.14= 1570/314= 5 cm

slant height (l) = 5 cm

Height of a cone (h) = √(l²) - (r²)

h = √ 5² -3²

h = √ 25 - 9 = √ 16 = 4 cm

h = 4 cm

Volume of cone= ⅓(πr²h)

= ⅓(3.14 × 3 × 3 × 4)

= 3.14 × 12= 37.68 cm³

Hence, the volume of a cone is 37.68 cm³.

Answer:

option d.......................

Answer: D

Step-by-step explanation:

Use SOHCAHTOA

We are given the opposite of the angle and the hypotenuse. We can use the sine function to acquire the value of x°.

sin(x) = 7/13

Take the inverse sine on both sides by using a calculator to get:

x = 32.58°

Answer:

32.58° that the answer hope this helps

Answer:

The easiest way of solving this is to eliminate one of the variables.  If you multiply each of the equations by a number so you can add the equations together and have only one variable left, you can solve the single variable equation.  Try multiplying the first equation by 11, the second by -10 and adding them, thus eliminating the y  variable.  After this, substitute that value you have for x and solve for y.  I hope this helps.

Answer:

The question is not correct. you have two linear functions. do you want to know their intersection point?

Step-by-step explanation:

[tex]f(x)=2x-6\\[/tex]

[tex]2x-6=0[/tex]

[tex]2x=6[/tex]

[tex]\frac{2x}{2} =\frac{6}{2\\}[/tex]

x=3

Then you just plug into g(x)

[tex]g(x)=x-2x[/tex]

[tex]g(x)=3-2(3)\\[/tex]

[tex]g(x)= 3-6[/tex]

So,

f(x)=3

g(x)=-3

Step-by-step explanation: happy to help let me know if you have any more questions.

Answer:

work= force ×distance

force= mass × acceleration due to gravity

mass= 1kg

acceleration=10

Force=1×10=10N

Work=10×2=20joules

The  work done is 20 joule.

What is Work done?

It should be converted to energy in order to move an object. Energy can be transferred by the use of force. Work done refers to the amount of energy used by a force to move an object.

Given:

mass, m= 1 Kg

So, force = mg = 1 x 10 = 10 N

and, displacement = 2m

Now, work done= force x displacement

                           = 10 x 2

                           = 20 Joules.

Hence, the work done is 20 joule.

Answer $390

Step-by-step explanation:

Answer:

$390

Step-by-step explanation:

First Roberto works 32 hours at 6.50 per hour. At that time, he earn 32*6.5 = $208. Then he works 8 hours at a time and a half. This means that his pay rate is 50% more, or 6.5*1.5 = $9.75 per hour. Since he worked 8 hours at this pay rate, he earns 8*9.75 = $78. And then he works 8 hours double time. This means his pay rate was doubled during that duration. 6.5*2 = 13, 13*8 = $104.

Total: 208 + 78 + 104 = $390

Answer: 22

Step-by-step explanation:

Answer:

Step-by-step explanation:

let fathers age now be x

daughters age now be y

10 years hence

(x+10)= 2(y+10)

x+10 = 2y+20

x-2y=10

10 years ago

(x-10)= 6(y-10)

x-10 = 6y-60

x-6y=-50

x-2y=10

x-6y=-50

subtract the equations

4y=60

y=15 daughter's age now

substitute y in x-2y=10

so x=40 present father's age

pls mark brainliest

Answer:

Let the age 10 years ago of daughter be ( x years ) and age of father would be ( 6x years )

After 10 years, age of father = ( 6x + 10 + 10 )

= ( 6x + 20 ) years

And Age of daughter will be = ( x + 10 + 10 )

= ( x + 20 ) years

ATQ,

6x + 20 = 2( x + 20 )

=> 6x + 20 = 2x + 40

=> 6x - 2x = 40 - 20

=> 4x = 20

=> x = 5

Hence, Present age of daughter = ( x + 10 )

= ( 5 + 10 )

= 15 years

Present age of father = ( 6x + 10 )

= 6( 5 ) + 10

= 30 + 10

= 40 years

10x + 7y = 9 —— (1)

-4x -7y = 9 —— (2)

6x = 18

x = 18/6

x = 3

put x=3 in (1)

10(3) + 7y = 9

30 + 7y = 9

7y = 9 - 30

7y = -21
