Question

What is the area of the hemisphere?

Answer 1

Determining the area of the hemisphere.

A hemisphere is a 3D form that is half the size of a sphere and has one flat, round side.
The total surface area of a hemisphere is equal to the sum of its curved surface area and base area.

Hemisphere Area.

• Curved surface area(CSA) $=2\pi r^2$
• Total surface area (TSA) $=3\pi r^2$

Hence, the area of the hemisphere is $2\pi r^2$ and $3\pi r^2$.
