(12C Platinum) Circles and Spheres - Gamo - 12-02-2018 10:49 AM
Program solution for Circles and Spheres with givin Radius.
1. Circles solve for Circumference and Area
Circumference = 2 * Pi * r
Area = Pi * r^2
2. Spheres solve for Surface Area and Volume
Surface Area = 4 * Pi * r^2
Volume = 4/3 * Pi * r^3
----------------------------------------
Procedure:
Input Radius [R/S] display 1111 briefly then 0.00
[RCL] 1 Answer Circle Circumference
[RCL] 2 Answer Circle Area
[RCL] 3 Answer Sphere Surface Area
[RLC] 4 Answer Sphere Volume
Example:
Circle Radius = 3
3 [R/S] display "1111" 0.00
[RCL] 1 Answer 18.85 // Circle Circumference
[RCL] 2 Answer 28.27 // Circle Area
---------------------------------------
Sphere Radius = 3
No need to press [R/S] since same radius from previous example.
[RCL] 3 Answer 113.10 // Sphere Surface Area
[RCL] 4 Answer 113.10 // Sphere Volume
