A hemispherical dome of a building needs to be painted (see Fig. 13.21). If the circumference of the base of the dome is 17.6 m, find the cost of painting it, given the cost of painting is Rs 5 per 100 `c m^2`

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Find the radius of the hemispherical dome.
Given the circumference of the base of the dome is 17.6 m. The formula for the circumference \( C \) of a circle is given by:

\[ C = 2\pi r \]
