What is the output of this program?

class area {
public static void main(String args[])
{
double r, pi, a;
r = 9.8;
p1 = 3.14;
a = pi * r * r;
System.out.println(a);
}
}
a) 301.5656
b) 301
c) 301.56
d) 301.56560000

• a)301.5656
  
  In java it will only print 301.5656.
  because in java double will only print upto it finds zero after decimal
  Try it yourself on java compiler

• compilation error. cause pi value not specified instead of p1 specified . otherwise it will be 301.5656
• 10 years agoHelpfull: Yes(9) No(0)
• d)301.56560000
  since double value gives ans. in 8 places after decimal
• 10 years agoHelpfull: Yes(6) No(5)
• d)301.56560000
• 10 years agoHelpfull: Yes(2) No(5)
• a=pi*r*r, pi=3.14 , r=9.8 then a=3.14*9.8*9.8 a=301.5656
• 10 years agoHelpfull: Yes(2) No(1)
• d)301.56560000
• 9 years agoHelpfull: Yes(2) No(1)
• a)301.5656
  and the program having error p1 is not defined so correct it to pi.
• 10 years agoHelpfull: Yes(1) No(1)
• d
  because it is defined that a is double. and double value having 8 places after decimal.

• a)301.5656
• 10 years agoHelpfull: Yes(0) No(0)
• Since the datatype is double...answer is 301.5656
• 10 years agoHelpfull: Yes(0) No(0)
• a.
  pi*r*r=a is nothing but the values given by the programmer to calculate
  i.e,. 3.14*9.8*9.8=301.5656
• 10 years agoHelpfull: Yes(0) No(0)
• 301.5656 simply putting the values in formula.
• 9 years agoHelpfull: Yes(0) No(0)
• the answer for sure is A
• 9 years agoHelpfull: Yes(0) No(0)
• answer is (d) because of double numeric data type
  
• 9 years agoHelpfull: Yes(0) No(0)
• answer is a
  
• 9 years agoHelpfull: Yes(0) No(0)
• ans a) 301.5656
• 9 years agoHelpfull: Yes(0) No(0)
• it can not be executed.if we use static block then it will compile but it can not be executed.

• 9 years agoHelpfull: Yes(0) No(0)
• a option is the answer.
  to submit the values and simplyfy that...
  u can get the value is 301.5656
  a=3.14*9.8*9.8
  =301.5656
• 9 years agoHelpfull: Yes(0) No(0)
• Option A is right because 9.8*9.8*3.14=301.5656 i.e :after . there are four digits so after four digits(from left ) . is placed
• 9 years agoHelpfull: Yes(0) No(0)
• compile error because p1 is undefined

  Pi*r*r
• 8 years agoHelpfull: Yes(0) No(0)
• 301.5656. It will calculate a. As given a= pi*r*r. and the value of pi is 3.14.the answer will be 3.14 *9.8*9.8

• 7 years agoHelpfull: Yes(0) No(0)
• a 301.5656
• 7 years agoHelpfull: Yes(0) No(0)
• a because on execution of loop it yields the value 301.5656
• 7 years agoHelpfull: Yes(0) No(0)
• Ans = 301.5656
• 7 years agoHelpfull: Yes(0) No(0)
• error
  there is no value(pi)

  In java it will only print 301.5656.
  because in java double will only print upto it finds zero after decimal

• answer :a
  301.5656
• 5 years agoHelpfull: Yes(0) No(0)
• option a is correct
  a=3.14*9.8*9.8
  a=3.14*96.04
  a=301.5656
• 4 years agoHelpfull: Yes(0) No(0)

• d will be answer
• 3 years agoHelpfull: Yes(0) No(0)
• 3.14 x 9.9 x 9.8 = 301.5656
• 3 years agoHelpfull: Yes(0) No(0)
• r = 9.8 * 9.8 = 96.04.
  pi = 3.14
  
  a = 96.04 * 3.14
  a = 301.5656
