Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
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
