The radius of a circular garden is 42 m. The distance (in m) covered by running 8 rounds around it, is: (Take π = $\frac{22}{7}$)
Answer & explanation
Correct answer: option 4
We have,
Radius of the circular garden r = 42 m
Circumference of circular garden = 2 × \(\frac{22}{7}\) × 42 = 264 m
1 round cover the distance = circumference of the circular garden = 264 m
8 round cover the distance = 8 × 264 = 2112 m
