# Hemisphere Volume & Surface Area Calculator

getcalc.com's **Hemisphere Formulas & Calculator** is an online basic geometry tool to calculate volume & surface area of a half-sphere shape, in both US customary & metric (SI) units.

## Steps to Find Volume and Surface Area of a Hemisphere

The step by step workout for how to find what is the volume and surface area of a hemisphere.__Workout :__

step 1 Address the formula, input parmaeters & values

Radius = 5 in

step 2 Apply radius values in Volume formula

Volume V = 2πr³/3

= 2 x 3.1416 x (5)³/3in³

= 2 x 3.1416 x 125/3in³

= 785/3in³

Volume V = 261.7994 in³

step 3 Find Surface area using below surface area formula

Surface Area = 2πr²

= 2 x 3.1416 x (5)² in²

= 2 x 3.1416 x 25 in²

Surface Area = 157.0796 in²

## Definition & Formulas

**Hemisphere** is a three dimensional plane or geometric shape represents exact half of a sphere.
