bad test. to get the test answer you must square the diameter and multiply it by pi, intead of pi*r^2(or pi*d/2^2)

For this problem, you have taken x as diameter, but answer is correct when you take x as radius. So, please improve your correct answer code.

i think, the question should be updated.It should be written radius instead of diameter....

Hi,

the area of a circle is defined by:

A = (pi)*(r^2)

--> for d = 2 like in your test suite that means:
r = d/2 --> r=1
--> r^2 = 1
--> multplied by pi = 1*pi

so A(d=2) = A(d/2) = A(r) = r^2 * pi = 1^2 * pi = 1 * pi = pi

not 4*pi like your solution suggests.

Your solution would be correct for R=2 - not D=2 - you should correct this. Ether you change the description that the diameter is given (should be radius to be correct) or you change the Test suite inm order to give correct results.

best regards

The test suite is incorrect. It is either the surface area of a sphere given the diameter or the area of a circle given a radius.

Please correct the problem. According to the test case it's the radius that is given, not the diameter...

nice try

This user (ALBERT ALEXANDER STONIER) appears to have gamed the system, with fraudulent "likes" of this unremarkable solution submitted by 'sock-puppet' accounts. —DIV

I think , test suite is wrong according to the question statement.

Did you mean "the area of a sphere?"

More test cases need to be added.
