Answer:
12.5664 units (rounded off to four decimal values)
Step-by-step explanation:
Arc length = 2 × π × r × 
For our partial circle;
The radius (r) = 8 units
The central angle = 90°
Arc length = 2 × π × 8 × 
= 12.5663706144 units
Or 12.5664 units (rounded off to four decimal values)

Distribution of 500 visitors =100% attendees.
We remove a zero to find 1/10th. By converting 500 } 50/10 = 10 x 50
Step-by-step explanation:
when you add up; 40/10 + 25/10 = 4.0 + 2.5
and show 7.5 is the same as a + b + 1 x 100
and above 7.5 = 175/100 = 1 .75
Or use the counter x = multiply by 50
40/10 + 25/10 = 6.5
6.5-10 = 3.5
x =3.5 x 50
For this last one we can pose new question where 300 visitors was the original total then create new data for new question.
where x = multiply by 30 and create all to tenths etc.
We subtract the shown tenths only to find the total
Then same will apply above with new data.
