The formula for the area of the circle is:
Area=  \pi r^{2}
All you have to do is plug in 8 for r :)

Please help to solve it step by step, (show working) please help me
ANTONII [103]
I'm assuming you only need the first triangle. You didn't specify. If you need it after I answer the first one I'll be happy to help though.

To find the area of a triangle you go b(h)/2=a

6cm(3cm)/2
18/2
Area=9

To find the perimeter you add all of the sides together.

4+4+6=P
4+10=P
14= Perimeter

What is the value of x in the equation 1/5 x-2/3y = 30, when y = 15?
Svetllana [295]

Answer:

The value of x is 200 in the equation 1/5x - 2/3y = 30, when y = 15

Step-by-step explanation:

<u>Given</u>

equation: x - 2/3y = 30

when y = 15

<em>Plug in y:</em>

1/5x - 2/3(15) = 30

1/5x - 10 = 30

<em>add</em> 10 to both sides,

1/5x - 10 + 10 = 30 + 10

1/5x = 40

<em>multiply</em> both sides by 5

1/5x * 5= 40 * 5

x = 200

Examine the system of equations. y = 3 2 x − 6, y = −9 2 x + 21 Use substitution to solve the system of equations. What is the v
nadezda [96]

Answer:

<h2>y = -4/9</h2>

Step-by-step explanation:

Given the system of equations y = 3/2 x − 6, y = −9/2 x + 21, since both expressions are functions of y, we will equate both of them to find the variable x;

3/2 x − 6 = −9/2 x + 21,

Cross multiplying;

3(2x+21) = -9(2x-6)

6x+63 = -18x+54

collecting the like terms;

6x+18x = 54-63

24x = -9

x = -9/24

x = -3/8

To get the value of y, we will substitute x = -3/8 into any of the given equation. Using the first equation;

y = 3/2x-6

y = 3/{2(-3/8)-6}

y = 3/{(-3/4-6)}

y = 3/{(-3-24)/4}

y = 3/(-27/4)

y = 3 * -4/27

y = -4/9

Hence, the value of y is -4/9
