circumference= 2πr
=2 × 22/7 × 35
=220 cm
now,
no of revolution= 1.65 × 100000/220
=16500/22
=1500/2 =750
=2 × 22/7 × 35
=220 cm
now,
no of revolution= 1.65 × 100000/220
=16500/22
=1500/2 =750

diameter of wheel = 70 cm
radius of wheel = 70 /2 = 35 cm
=) circumference of wheel =2πr
= 2× 22/7 × 35
=2×22×5
= 220 cm
1 revolution = circumference
number of rev. = distance / circumference
n = 1.65 ×1000 × 100 / 220 = 7500
so number of revolution is 7500 ans
radius of wheel = 70 /2 = 35 cm
