This problem was solved incorrectly. for this problem, circle the mistake in the work/answer, explain what the mistake is, and find the correct answer. use 3.14 for pi and round to the nearest hundredth where necessary

The mistake was that 12² was calculated incorrectly. 12² means '12 squared', which is 12 × 12. Of course, 12 × 12 is 144, but the student worked out 12 × 2, which is 24.

Therefore, to work out the correct answer, the student has to replace 24 with 144 and continue to work out the

A = πr²

A = 3.14 · 12²

A = 3.14 · 144

A = 452.16 yd²

the mistake is that the person multiplied 12 by 2 instead of multiplying 12 by 12, therefore their answer is incorrect.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
