App description

Ball fan surface area and volume calculation formula:

\(S=πr(2h+ \frac {d1}{2} )\)

\(S1=π \frac {d1}{2} r\)

\(V= \frac {2}{3} πr^2h\)

In the formula:

• r - radius of the ball
• d1—the diameter of the bow bottom circle
• h—high bow

Usage example

Input data:

R—sphere radius: 4

D1—the diameter of the bow bottom circle: 6

H—bow height: 7
