Volume of a cylinder is pi*(r^2)*h

h>5.5r+r ---> h>6.5*3.4

So, volume is > 3.14*3.4*3.4*6.5*3.4=800 (approx)

Hence, answer will be D.

Answer is D : 700 < V < 900

Volume of cylinder is \(\pi\)\(r^2\)h

Given r = 3.4 and h is 550% more than r, which means r = 6.5 * r (if 100% more then it means twice, so..)

So V = \(\pi\)\({3.4}^2\)* 6.5

You forgot to multiply 3.4 one more time (value of r)

Height=3.4*6.5=22.1

Volume = pi*r^2*h=pi*3.4^2*22.1= approx 800

Answer: D

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 = 6.5 * 3.4 ~ 21

So 22/7 * 12 * 21 = 792

so answer should be

D. 700 < V < 900
