The radius of a pulley is 202 mm. Find the circumference of the pulley. (This is the amount of rope that passes through the pulley as it rotates exactly once.)

Answer 1

Circumference = 2πr = 2π(202 mm) = 1262.4 mm

Answer 2

Yes

Answer 3

NO

Don't know how the bot does basic arithmetic, but I get ...

C = 2π (202) = 1269.2 mm
