## Program based upon variables declaration and initialization

- Create a program to declare and initialize variables for given formulas and also print them.
**Circle**- area= πr
^{2} - perimeter = 2*π*r

- area= πr
**Square**- area= side * side
- perimeter = 4*side

**Rectangle**- area= length * width
- perimeter= 2*(length + width)

**Right angle triangle**- area= (base*height)/2
- perimeter= side1+side2+side3

**Volume**- Cube
- v=a
^{3}

- v=a
- Cylinder
- v=b*h

- Cone
- v= b*h/3

- Sphere
- v=4πr
^{3}

- v=4πr
