Answer:
5.25 is the lenght of the arc AB.
Step-by-step explanation:
First, since we are told the answer should be expressed in radians, we need to convert the arc angle into radians, we do that by multiplying the angle by π and dividing by 180.
60° * π/180 = 1.05rad
Now, there is a simple formula to calculate the arc lenght, A = Ф*r, where:
A = arc lenght
Ф = arc angle (60°=1.05rad)
r = radius (5cm)
A = 1.05*5cm
A = 5.25cm

Download photomath on Appstore it'll help you explain. but basically you multiply each digit at the bottom to the whole number on the top
23.50
<u>x </u><u>23.74</u>
940 ====== 23.50 multiply to 4
16450 ====== 23.50 multiply to 7
70500 ====== 23.50 multiply to 3
<u>+ 470000 </u> ====== 23.50 multiply to 2
557.890 ====== Add all the numbers together, move the decimal sign down to align with the result
