☆Hello friend☆
Converting 4.5 km into m = 4.5×1000
= 4500 m
Distance covered in 1500 revolution = 4500m
Distance covered in 1 revolution = 4500m/1500
= 3m
Circumference= 2×22/7 × r
3m × 7/22 × 1/2 = r
21/44 m = radius
Converting 4.5 km into m = 4.5×1000
= 4500 m
Distance covered in 1500 revolution = 4500m
Distance covered in 1 revolution = 4500m/1500
= 3m
Circumference= 2×22/7 × r
3m × 7/22 × 1/2 = r
21/44 m = radius
