Volume formula for a cylinder is V=(pi)r^2(h) I am going to move the value of h out in front of pi so it is easier for you to see. Therefore our formula will come out to: 150=(7.4)(3.14)r^2 Now we can multiply 7.4 times 3.14 150=23.236r^2 Now we divide that number on both sides 6.4555=r^2 Finally we square root both sides to get the radius 2.5407676 cm The question never specified rounding. So, I wrote out a few decimal spaces
