We know that

length of circumference=2*pi*r
for r=18 cm
length of circumference=2*pi*18--------> 36pi cm

if 2pi radians (full circle)------------------> has a length of 36pi cm
(3/2)pi radians---------------------------> X
X=(3/2)pi*36pi/2pi----------> x=27pi cm

the answer is
27pi cm

How do you isolate a variable?
Talja [164]

Answer:

"The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation."

Step-by-step explanation: That was from google :3

Given the system of equations, what is the solution?5x - 4y = 7x = 5 - 3/2y
nignag [31]

9514 1404 393

Answer:

  (x, y) = (61/23, 36/23)

Step-by-step explanation:

We assume you intend the equations to be ...

  • 5x -4y = 7
  • x = 5 -3/2y

Then in general form, they are ...

  5x -4y -7 = 0

  2x +3y -10 = 0

The solution using the "cross multiplication method" is ...

  1/(15 +8) = x/(40+21) = y/(-14 +50)

  (x, y) = (61/23, 36/23)

_____

<em>Comment on "cross multiplication method"</em>

When the coefficients from the general form equations are written as a 2×4 array with the first and last columns the same ...

  \left\{\begin{array}{cccc}5&-4&-7&5\\2&3&-10&2\end{array}\right\}

the solution is 1/d1 = x/d2 = y/d3, where d1, d2, d3 are the determinants of successive pairs of columns.

  • d1 = (5)(3) -(2)(-4)
  • d2 = (-4)(-10) -(3)(-7)
  • d3 = (-7)(2) -(-10)(5)
