See... diameter of park = 280 m

so, radius = 280/2= 140 m

l**ength of circumference = 2π×r**

= 2×(22/7)×140

=880 m

now,

**he runs 10 times around the park, so total distance covered by him = 10 ×880 = 8800 m**

1 km = 1000 m

so,** 8800 m = 8.8 km**

so, radius = 280/2= 140 m

l

= 2×(22/7)×140

=880 m

now,

1 km = 1000 m

so,
