Hemisphere

✅What is Hemisphere ?

A hemisphere is a three-dimensional shape that is formed by slicing a sphere in half along its equator. It is a half-sphere, meaning it has a curved surface that is exactly half of a sphere. The word "hemi" means half, so a hemisphere is literally "half a sphere".

✅Volume of a hemisphere:

👉Formula: V = (2/3)πr³

Where r is the radius of the hemisphere.

👉Example: If the hemisphere has a radius of 7 cm, then the volume would be V = (2/3)π(7 cm)³ = 718.81 cubic centimeters.

✅Surface area of a hemisphere:

👉Formula: A = 2πr²

Where r is the radius of the hemisphere.

👉Example: If the hemisphere has a radius of 7 cm, then the surface area would be A = 2π(7 cm)² = 307.86 square centimeters.
