**Area of a circle = ****πR ^{2} **

**Where π = 3.14 and R = radius of circle**

**Example**:

Radius = 4.0 Area = π*radius*radius = 3.14*4*4 = 50.24

**Code**:

public class AreaOfCircle { | |

public static void area(double radius){ | |

double pi = 3.14; | |

double area = pi*radius*radius; | |

System.out.println("Area of circle with radius="+radius + " is: " + area); | |

} | |

public static void main(String[] args) { | |

double radius = 4; | |

area(radius); | |

} | |

} |

**Output**:

Area of circle with radius=4.0 is: 50.24
