A circular room has a floor of diameter 590cm. Estimate the 92.2 perimeter of the room in metres

  18.5 m

Step-by-step explanation:

The diameter in meters is 5.90, so the circumference of the room is ...

  C = πd = 5.90π m ≈ 18.5 m

The perimeter of the room is about 18.5 m.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
