Area and Perimeter of different Shapes

You will be given asked to chose a geometrical shape. (1: Circle, 2:Rectangle, 3: Isosceles Triangle) Calculate the area and perimeter of the selected object.

Question:
First ask for the Object Type;

  1. if 1 is given then ask for the radius and
    calculate the area and perimeter of the circle;
  2. if 2 is given then ask for the width and height and
    calculate the area and perimeter of the rectangle;
  3. if 3 is given then ask for the base and height of an isosceles Triangle
    calculate the area and perimeter of it

Input specification
You will be given an integer number (objType) where 1 ≤ objType ≤ 3, according to the given object type you will be given one (circle) or two integer numbers (rectangle or triangle).
Note: PI= 3.14159

Output specification
Find out the area and perimeter of the given shape. Your result should contain at most 3 decimal place after the floating point.

Sample Input I
