Question

in a 3 mark question how many marks would be deducted if by mistake we have taken the value of pi wrong and whole procedure is correct??​

Answer 1

Explanation:

in my point of view I think nearly 2 to 2. 5 marks will be deducted because in maths even small mistakes can lead to the huge differences in the answers but if the value is pi is near in its original value I think that teacher can give you a few more marks

Answer 2

If pi value is wrong then the whole answer will be wrong......
Maybe 2-2.5 marks might be deducted...
