You can put this solution on YOUR website!

We can use formula: V=%28pi%29r%5E2%2Ah (*straw is a cylindrical shape)
Then,
5cm%5E3=%28pi%29r%5E2%2819.5cm%29--->
r%5E2=5cross%28cm%5E3%29cm%5E2%2F61.23cross%28cm%29=0.081659cm%5E2
r=sqrt%280.081659cm%5E2%29=0.28576cm, radius
Then, d=2r=2%280.28576%29=highlight%280.51752cm%29, Answer
