You should calculate( the area of a circle of radius 15 cm ) minus the area of the circle of radius (15 cm - width of the frame). I am not able to read the number, sorry.
That is the surface area of the frame.

Then, if area of circle radius is 100%, the % of face of the clock is:

(100xareaCircle(15cm-widthframe))/areaCircle15cm

How to convert 3.248 repeating decimal with 48 repeating into a simplified fraction

Sonja [21]

Answer:

$x=\frac{536}{165}$

Step-by-step explanation:

Let X be the value of 3.2484848.... infinite times

Multiply by 100

$x=3.24848....\\100x = 324.8484.....$

Subtract to get

$100x-x = 324.8484...-3.248484....\\99x = 321.60\\x=\frac{321.6}{99} \\x=\frac{1072}{330} \\x=\frac{536}{165}$

Thus the number 3.248 repeating decimal with 48 repeating in fraction form is

$\frac{536}{165}$
