9514 1404 393

Answer:

  • 150 children
  • 200 adults

Step-by-step explanation:

The equations can be written as ...

  y = 350 -x . . . . . . . . total number of people

  4x +2y = 1100 . . . . . admission fees collected

Substituting for y, we have ...

  4x +2(350 -x) = 1100

  2x = 400 . . . . . . . . . . . . subtract 700, collect terms

  x = 200

  y = 350 -200 = 150

150 children and 200 adults attended the fair.

The area of a circle is 36/pi cm^2 What is the radius of the circle?
Lady bird [3.3K]

Answer:

the  radius of the circle is 6cm

Step-by-step explanation:

the area of a circle is given to be  = 36πcm²

radius of the circle = ?

to find the radius of the circle lets start by applying  the formula for finding the area of a circle.

area of a circle = πr²

36πcm² = πr²

36π = πr²

divide both sides by π

36π/π = πr²/π

36 = r²

to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36

r² = 36

r =√36

r = 6cm

therefore the  radius of the circle is 6cm
