Answer : 0.53m/s

First we convert 33 rpm into radians per second.We note that there are $2\pi$ rad/rev and 60s in 1 min.The conversion gives an angular frequency of $3.454rad/s$.Now we convert the radius to meters so that we are in SI units(MKS).Thus,R=0.1525m.Now we know that,for uniform circular motion,$v=R\omega$,so

$v=(0.1525m)(3.454rad/s)=0.53m/s$
