 Hemisphere Calculator is an online tool which can calculate the surface area and the volume of hemisphere from the radius of the hemisphere.

## Procedure

Step 1 :

Apply these formulas -

Total surface area of hemisphere = 3 × π × r2

Volume of hemisphere = (2/3) x π x r3

Where π = 3.14, r = radius.

## Example Problems

1. ### Find the volume and total surface area of a hemisphere, whose radius is 3cm.

Step 1 :

Apply formula for the volume of hemisphere = (2/3) x π x r3

Putting π = 3.14 , r = 3cm;

Volume of hemisphere = (2/3) × 3.14 ×  33 cm3

Volume of hemisphere = (2/3) × 3.14 × 27 cm3

Volume of hemisphere = 56.52 cm3

Now apply formula for the total surface area of hemisphere = 3 × π × r2.

Putting π = 3.14 , r = 3cm;

Total surface area of hemisphere = 3 × 3.14 ×  3cm2

Total surface area of hemisphere = 3 × 3.14 × 9 cm2

Total surface area of hemisphere = 84.78 cm2

Volume=56.52 cm3 & Total surface area = 84.78 cm2.

2. ### Find the total surface area of hemisphere, whose radius is 8 cm.

Step 1 :

Apply formula for the total surface area of hemisphere = 3 × π × r2

Putting π = 3.14 , r = 8cm.

Total surface area of hemisphere = 3 × 3.14 ×  82 cm2

Total surface area of hemisphere = 3 × 3.14 × 64 cm2
