# Sphere Belt Volume and Surface Area Online Calculator

Category:

### App description

Sphere volume and quantitative calculation formula:

$$V= \frac {πh}{b} (3r1^2+3r2^2+h^2)$$

$$S1=2πRh$$

$$S=2πRh+π(r1^2+r2^2)$$

• where
• R - the radius of the ball
• r1, r2 - ground radius
• h - waist height
• h1 - the distance from the heart O to the bottom center O1

### Usage example

Input data:

H—waist height: 8

H1—distance from the center of the sphere O to the center of the circle O1: 9

Click "Calculate" to output data

Sphere body side surface area: 201.06

Missing surface area of the ball: 342.43

Sphere body volume: 833.56
