The minute hand of a clock is 7 inches long. how far does the tip of the minute hand move in 35 minutes? if necessary, round the answer to two decimal places.

An hour is 60mins or 1 rotation

so

the hand moves 35/60 of the circumference of the clock

so

c=2pir

r=length of hand=7

c=2pi7

c=14pi

then, we have 35 out of 60 mins or 35/60=7/12

7/12 times 14pi=98pi/12=49pi/6≈25.66 inches
