Answer 2

Given:

Thickness of the hemisphere = 0.25 cm

Inner radius = 5 cm

To Find:

Find the curved surface area of the hemisphere

Solution

So,

The outer radius:

Outer radius = 5 + 0.25

Outer radius = 5.25 cm

The CSA:

Curved Surface Area = 1/2 x ( 4πr² )

Curved Surface Area = 2πr²

Curved Surface Area = 2π (5.25)²

Curved Surface Area = 173.25 cm²
