Answer:
60?
Step-by-step explanation:
2πr = 163.28
20(2πr) = 3265.6
r ≈ 60.927382
Answer:
25.99 metres
Step-by-step explanation:
2πr is the circumference equation for the distance of one lap. Multiply that by 20 to get the distance of the laps in total. Then, simplify with r (radius) as the variable to solve for.
20(2πr) = 3265.6
2πr = 163.28
r ≈ 25.986819108
