A Hemisphere is a half sphere, one half of a sphere or globe that is divided by a plane passing through its center.

Calculate the area, volume of Hemisphere (Hemisphere Calculator)

Formula

**Volume of Hemisphere** = (2/3)πr³

**Curved Surface Area(CSA) of Hemisphere** = 2πr²

**Total Surface Area(TSA) of Hemisphere** = 3πr²

**where,**

r = radius, π = 3.14

A Hemisphere is a half of a sphere on one side of a great circle. I geometry, hemisphere is defined as an exact half of a sphere. It also refers to half of the earth, such as the Northern Hemisphere and Southern Hemisphere.

**Examples:**

Find the volume, curved surface and total surface area of a hemisphere with the given radius 2.

**Step 1:** Find the volume.

Volume = (2/3)πr³ = (2/3) * 3.14 * 2³ = 0.67 * 3.14 * 8 = **16.8304**

**Step 2:** Find the curved surface area (CSA).

Curved Surface Area(CSA) = 2πr² = 2 * 3.14 * 2² = 6.28 * 4= **25.12**

**Step 3:** Find the total surface area (CSA).

Total Surface Area(TSA) = 3πr² = 3 * 3.14 * 2² = 9.42 * 4 = **37.68**
