A hemispherical bowl is made of steel, 0.25 cm thick. The inner radius of the bowl is5 cm. Find the outer curved surface area of the bowl.

Explanation

To find the outer curved surface area of a hemispherical bowl made of steel, we will follow these steps:

### Step 1: Determine the outer radius of the bowl
The inner radius of the bowl is given as 5 cm, and the thickness of the steel is 0.25 cm. Therefore, the outer radius (R) can be calculated as:
\[ R = \text{Inner radius} + \text{Thickness} = 5 \, \text{cm} + 0.25 \, \text{cm} = 5.25 \, \text{cm} \]
