168 papers x papers
------------------ = -----------------
21 minutes 10 minutes
168*10 = x * 21
1680 = 21x
Divide each side by 21
1680/21 = 21x/21
80 = x

The area of a circle can be found using:
pi x r^2 (where r is the radius)
If the area of the circle is 255pi, then:
pi x r^2 = 255pi
Now we need to make r the subject:
r^2 = 255 (cancel the pi on both sides)
r = square root of 255
r = 15.96871942
Answer: 15.96871942 feet
Hope the answer helps :)
