of 50 customers surveyed, 22 of them stated that they would buy a protection
plan.
On the next day, 700 customers came.
Let’s predict how many of them would probably buy the protection plan.
Ratio = 50 : 22 = 700 : x
=> 700 * 22 = 15 400
=> 15 400 / 50 = 308
Thus, if 700 customer came in the next day, around 308 of the customers will
buy life plan.</span>

Step-by-step explanation:
The CIRCUMFERENCE OF A CIRCLE is the distance round the circle.
It has the formular 2πr.
were r = radius
C = 2πr
72 = 2 × 3.142 × r
72 = 6.284r
dividing bothsides by 6.284
r = 72/ 6.284
r = 11.457
AB is an arc.
Lenght of an arc
