(b) What temperature change is required to increase its volume by 1.1%?

I got the first answer right.

i am having trouble understanding how to figure out how much the diameter is increased by when i know how much the total volume is increased by.....

Take the cube root of the volume increase factor
(1.011)^1/3 = 1.0036533.

That will be the diameter increase factor. The increase will be 0.3653%
