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] 3 Answer Sphere Surface Area

Example:

3 [R/S] display "1111" 0.00

[RCL] 1 Answer 18.85 // Circle Circumference
[RCL] 2 Answer 28.27 // Circle Area

---------------------------------------

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

--------------------------------------
Program: Circles and Spheres (ALG Mode)
Code:
``` STO 9 355 ÷ 113 = STO 0 x 2 x RCL 9 = STO 1 ------------------------- RCL 9 X^2 x RCL 0 = STO 2 ------------------------- RCL 9 X^2 x RCL 0 x 4 = STO 3 ------------------------- RCL 9 Y^X 3 x RCL 0 x (4 ÷ 3) = STO 4 1111 PSE CLx FIX 2```
