V is the volume of a cylinder; the radius of the cylinder is 3.4. The height of the cylinder is 450% more than the radius. Which of the following is true?
Choose the correct answer.
A) 700 < V < 900  B) 300 < V < 500  C) 500 < V < 700  D) 100 < V < 300  E) 900 < V < 1100
As we see the answers are in form of range we can use approximation   Volume of cylinder is πr^2h   Given π= 22/7 and r = 3.4 so r^2 ~ 12 and h = 5.5 * 3.4 ~ 19   So 22/7 * 12 * 19 ~ 717   so answer should be   A. 700 &lt; V &lt; 900   700 &lt; V &lt; 900nswer : 700 &lt; V &lt; 900
