Best ResponseYou've already chosen the best response.2here we have to apply this formula: \[C = 2 \times \pi \times 1.4 = ...inches\]

Best ResponseYou've already chosen the best response.2no, please we have to do this computation: \[C = 2 \times \pi \times 1.4 = 2 \times 1.4\pi = 2.8 \times \pi \;inches\]

Best ResponseYou've already chosen the best response.2oops.. \[C = 2 \times \pi \times 1.4 = 2 \times 1.4\pi = 2.8 \times \pi \;meters\]

Best ResponseYou've already chosen the best response.2here 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

Best ResponseYou've already chosen the best response.2you don't have to multiply 2.8*3.14

Best ResponseYou've already chosen the best response.0okay, without pi it would be 2.8 which would be D ;D
