The circumference is (2)(pi)(r) which is 2(3.14)(12) which equals 75.36 cm. So your velocity is 2.4(75.36) cm/s. so Ac= 2.4(75.36)/ 12 and that is about 15 cm^2/s. And the direction is always towards the centre of the circle. Centripetal acceleration is just Ac=v^2/r. The circumference is (2)(pi)(r) which is 2(3.14)(12) which equals 75.36 cm.
