# Sphere Volume & Surface Area Calculator

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

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

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

step 1 Address the formula, input parmaeters & values

Radius = 5 in

step 2 Apply radius values in Volume formula

Volume V = 4πr³/3

= 4 x 3.1416 x (5)³/3in³

= 4 x 3.1416 x 125/3in³

= 1571/3in³

Volume V = 523.5988 in³

step 3 Find Surface area using below surface area formula

Surface Area = 4πr²

= 4 x 3.1416 x (5)² in²

= 4 x 3.1416 x 25 in²

Surface Area = 314.1593 in²

## Definition & Formulas

**Sphere** is a three dimensional plane or geometric shape represents either a solid or hallow round object with every point on its surface in equal distance from its center.
