we know formula for circumference as
we are given
C=24.8
and then we can solve for r
now, we can use area formula
we can plug r
and we get
So,

NO 2+2 = 22
Step-by-step explanation:
The percentage increase from 5 laps of race on the first day to 9 laps after several weeks is 80%
<h3>How to determine the percentage increase?</h3>
The distance ran are given as:
Initial = 5 laps
Final= 9 laps
The percentage increase is calculated using:
Percentage = (Final - Initial)/Initial
So, we have:
Percentage = (9 - 5)/5
Evaluate
Percentage = 0.8
Express as percentage
Percentage = 80%
Hence, the percentage increase is 80%
