the answer will be 4.63 it can also be wrong

Answer 2

First off do 56cm x $\pi$ you'll get about 175.929188601 you'll need a calculator to keep it accurate

km to m is times a 1000 then m to cm is times 100 so 2.2 km to cm will be 220,000cm

then of course use your calculator and input this

220000 ÷ (56x$\pi$)

your answer will be 1250.5031... times
