V is the volume of a cylinder; the radius of the cylinder is 4.5. The height of the cylinder is 550% more than the radius. Which of the following is true? Choose one
A) 100 < V < 300	B) 300 < V < 500	C) 500 < V < 700	D) 700 < V < 900	E) 900 < V < 1900
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 = 4.5 so r^2 ~ 20 and h = 6.5 * 4.5 ~ 29   So 22/7 * 20 * 29 ~ 1823   so answer should be   E. 900 &lt; V &lt; 1900   Answer : 900 &lt; V &lt; 1900
