Question 412209
The clock is a circle and the length of the minute hand is the radius of this circle. Since 45 minutes is 3/4 of an hour the tip of the minute hand travels 3/4 of the way around the full circumference of the circle. Since circumference of a circle is {{{2pi*r}}}, the tip of the minute hand travels:
{{{(3/4)(2*pi*1.3)}}} centimeters
All you have to do is replace {{{pi}}} with a decimal (3.14159....), simplify the expression and round off your answer. I'll leave that up to you.
