Aminute-hand is 16 in long. find the distance traveled by the tip of the minute-hand in one hour.

consider the length of the minute hand the radius of a circle

 the diameter would be 16*2 = 32 inches

 circumference ( distance around the circle) =

PI *32

using 3.14 for PI

3.14 *32 = 100.48 inches  Round the answer as needed

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
