The number \pi is defined exactly as the ratio betweent the circumference and the diameter. We deduce that

\pi=\dfrac{C}{d}\iff C=\pi d

So, your cimference is 2\pi. You can use the approximation \pi=3.14 to round to the nearest hundredreth: 2\pi\approx 6.28

Adult tickets to Space City amusement park cost x dollars. Children's tickets cost y dollars. The Garcia family bought 3 adult a
KengaRu [80]

let the number of adult tickets be x and the number of children tickets be y

3x + y = 164...equ(1)

2x + 3y = 174....equ(2)

multiplying equation 1 by 3

9x + 3y = 492

subtracting equation 2 from 1

7x = 318

x = 45.43 dollars

substituting the value of x into the equation

3(45.428) + y = 164

y = 164 - 3(45.428)

∴y  = 27.71 dollars
