Need help with rotational kinematics and energy

Question

A 2.40 kg disc 1.10 m in diameter is rolling to the right without slipping on a horizontal floor at a steady 2.70 rad/s.

I found how fast the center of mass was moving which was 1.49 m/s

b. What is the center of mass kinetic energy of the disc?

c. What is the rotational kinetic energy of the disc?

d. What is the total kinetic energy of the disc?

Answer 1

d. total kinetic energy = 2.65 J + 1.32 J = 3.97 J
