Answer:

Radius of cone is 6 cm

Step-by-step explanation:

[tex]\sf\small\underline\purple{Given:-}[/tex]

[tex]\sf{\leadsto Volume\:_{(cone)}=120π \:cm^3}[/tex]

[tex]\sf\small\underline\purple{Solution:-}[/tex]

To calculate the radius of cone . Simply by applying formula of volume of cone. As given in the question that height is 10 cm and it's volume is 120 π cm³.

[tex]\sf\small\underline\purple{Calculation\: begin:-}[/tex]

[tex]\sf{\leadsto Volume\:_{(cone)}=\dfrac{1}{3}\pi\:r^2\:h}[/tex]

Well, the area is 400m^2 so we know each side is 20 feet long. Then with that we can make a 40deg 40deg 90deg triangle with the side lengths 20, 20, and x. So, the proportion would be 20/1=x/rad2. This gives us x=28.28, so the fence is 28.28m long. Hope this helps :))

Mr Li is four times as old as his son. In five years time, the sum of their ages will be 60 years. How old are they now?

Answers

Answer:

Mr Li is now 40 years old

his son is now 10 years old

Step-by-step explanation:

x = age Li

y = age son

x = 4y

x+5 + y+5 = 60

x + y + 10 = 60

x + y = 50

4y + y = 50

5y = 50

y = 10

x = 4y = 4×10 = 40

A = pi r^2

Using 3.14 as an approximation for pi

A = 3.14 ( 6)^2

A = 3.14 *36

A =113.04

Answers

Answer:

I guess that we have the equation:

(1/3)^2 + 3^2 =

And we want to solve it.

Here just remember that:

3^2 = 3*3 = 9

then:

(1/3)^2 = (1/3)*(1/3) = 1/9

replacing these in the expression, we get:

(1/3)^2 + 3^2 = 1/9 + 9

If we want to write this as a single fraction, we can rewrite:

1/9 + 9 = 1/9 + (9/9)*9

           = 1/9 + 81/9 = (1 + 81)/9 = 82/9

The solution to the equation is 82/9. The equation is: [tex](1/3)^2 + 3^2.[/tex]Calculate the square of [tex](1/3): (1/3)^2 = 1/9[/tex]

Calculate 3 squared:

[tex]3^2 = 9[/tex]

Now, substitute these values back into the original equation:

[tex](1/3)^2 + 3^2 = 1/9 + 9[/tex]

To add these fractions, you need a common denominator. In this case, the common denominator is 9:

1/9 + 81/9 = (1 + 81)/9 = 82/9

So, the solution to the equation is 82/9.

Answer:

the remaining angle measures 60°

Step-by-step explanation:

x = boy count

x + 14 = girl

x + x + 14 = 86

2x + 14 = 86

2x = 72

x = 36

x + 14 = 50

36 boys and 50 girls

the 4 angles of a quadrilateral = 360°

115° + 115° + 70° + x = 360°

300 + x = 360°

x = 360 - 300

x = 60°

The remaining angle measures 60°

f(4.7) = 13.1

Step-by-step explanation:

essentially this is just 3x-1

plug in 4.7 for x... 3*4.7 = 14.1 then subtract 1 =

13.1

the issue is the || absolute value...

if the "X" x value is NEGATIVE in the problem, just remove the negative sign...

in other words f(-4.7)  = 3(4.7) - 1

Answer:

13.1

Step-by-step explanation:

f(x) = 3|x|- 1, x= 4.7

f(4.7) = 3|4.7|- 1 *replace x with 4.7

= 14.1 - 1. *multiply 3 x 4.7

= 13.1. *subtract 1 from. 14.1

C. x 2 + y2 – 5x + 4y + 8 = 0

D. x 2 + y2 – 42 – 5y + 10 = 0

Answers

Answer:

None Of the Above.

Step-by-step explanation:

As we know that the general equation of circle is

putting h=5 and k= 4 and r= 5

x² + 25 - 10x + y² +16 - 8y = 25

x² + y² - 10x - 8y + 16 = 0 is the answer.
