    I'm guessing 2 x 3.14 x 1.4 ?

    here we have to apply this formula: \[C = 2 \times \pi \times 1.4 = ...inches\]

    no, please we have to do this computation: \[C = 2 \times \pi \times 1.4 = 2 \times 1.4\pi = 2.8 \times \pi \;inches\]

    oops.. \[C = 2 \times \pi \times 1.4 = 2 \times 1.4\pi = 2.8 \times \pi \;meters\]

    C= 8.792=8.792 = 8.792

    here you have to multiply 2*1.4 only, so our answer is: \[C = 2 \times \pi \times 1.4 = 2 \times 1.4\pi = 2.8 \times \pi \;meters\] and we have finished

    2.8 x pi meters = 8.792 :I

    you don't have to multiply 2.8*3.14

    okay, without pi it would be 2.8 which would be D ;D
