Daphne has a rope that is 60 meters long. She wants to use it to mark the boundary of a circle whose radius is an integer. What' s the largest possible radius for her circle, in meters?
1 answer:
9514 1404 393
Answer:
9 m
Step-by-step explanation:
The relationship between radius and circumference is ...
C = 2πr
Daphne wants r an integer such that ...
60 m ≥ 2πr
r ≤ (60 m)/(2π)
r ≤ (30/π) m ≈ 9.549 m
The largest integer radius Daphne can use is 9 meters .
