Continuous Bodies: Standard Results & Variable Density

The centre of mass of solid hemisphere of radius 8 cm is x from the centre of the flat surface. Then value of x is __________.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 3

For a solid hemisphere, CM is at $\frac{3R}{8}$ from the centre of the flat face.
$x = \frac{3 \times 8}{8} = 3$ cm
