Because the diameter is 47 cm
so the radius is 2x
r = 94 cm
A = πr² / 2
A = (3.14) (94)² / 2
A = 13872.52 cm²
Answer: The answer is B. Taking a look at the diagram, we see that there are 18 people in the overlap section, where people are both subscribers and below 25000. Hence b = 34. There are 34 people in the right-hand section, where they are subscribers but have an income that is not below 25000 (I.e. Above 25000). Hence a = 34. Finally, c is just the total of that row, so 55 + 13 = 68 = c.

<u>Given:</u>
Number of pages read by Jack = 40 per hour
Rate of reading by Dave =3/5 of a page in a minute
<u>To find:</u>
The person who reads faster and by how many minutes.
<u>Solution:</u>
If Dave reads 3/5 of a page in a minute then in an hour he would read,
(60 minutes = 1 hour)
pages in an hour
The difference between pages read by Jack and Dave is 
Therefore, Jack reads faster than Dave by 4 pages.
A= 3
B=6
