For this case, we have that by definition, the circumference of a circle is given by:

Where:
d: Is the diameter of the circle given by 2r, that is, twice the radius.
If we have a circle with a diameter equal to 8cm, then the circumference is given by:

Option C

Given mapping is a function.
Domain: 
Range: 
Step-by-step explanation:
By observing Marco's mapping diagram we can see that every value in time is mapped to only one value in the cost. This means that there will be no repetition or same output to two different outputs so given mapping is a function.
<u>Domain:</u>
Domain is the set of all inputs of a function. Here time is input so domain of function is:

<u>Range:</u>
Range is the set of all outputs of the function on domain so the range of the given function is:

Hence,
Given mapping is a function.
Domain: 
Range: 
Keywords: Domain, range, function

Total time spent reading is = 8/9 hour
He spends 1/4 of the time reading world news. That is = 1/4 * 8/9 = 2/9 hour
Splits the remaining time equally. Remaining time = 8/9 - 2/9 = 6/9
Splitting it equally = 6/9 divided by 2 = 6/9 * 1/2 = 3/9 = 1/3
Time spent reading comic is = 1/3 hour
I hope this helps.
