Consider the circle with the radius of 30 cm what is the approximate circumference of a circle ​

60π ≈ 188.4955592

Step-by-step explanation:

Circumference of a circle is given by 2 ∙ π ∙ r

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

think about it deeply and passionately about this property
