Examples and Formulas

Here are the examples and formulas used for each calculation type:

1. Calculate V, L, A | Given r, h

Input:

• Radius (r)

  • Total Surface Area $A = 2 \times \pi \times 5 \times (5 + 10) = 471.239 \, \text{cm}^2$
    

2. Calculate h, L, A | Given r, V

Input:

• Radius (r)

  • Radius $r = \frac{251.327}{2\pi \times 8} = 5 \, \text{cm}$
    
  • Volume $V = \pi \times 5^2 \times 8 = 628.319 \, \text{cm}^3$
    
  • Total Surface Area $A = 2 \times \pi \times 5 \times (5 + 8) = 408.407 \, \text{cm}^2$
    

5. Calculate r, L, A | Given h, V

Input:
